hyb 39l128160ac/t 128-mbit 3.3v mobile-ram infineon technologies 1 2003-02 the hyb 39l128160ac mobile-ram is a new generation of low power, four bank synchronous dram organized as 4 banks 2mbit x16. these synchronous mobile-rams achieve high speed data transfer rates by employing a chip architecture that prefetches multiple bits and then synchronizes the output data to a system clock. all of the control, address, data input and output circuits are synchronized with the positive edge of an externally supplied clock. operating the four memory banks in an interleave fashion allows random access operation to occur at higher rate. a sequential and gapless data rate is possible depending on burst length, cas latency and speed grade of the device. auto refresh (cbr) and self refresh operation are supported. the device operates with a single 3.3 v 0.3 v power supply. compared to conventional sdram the self-refresh current is further reduced. the mobile-ram devices are available in fbga ?chip-size? or tsopii packages. high performance: 8mbit x 16 organisation vdd = vddq = 3.3v fully synchronous to positive clock edge four banks controlled by ba0 & ba1 programmable cas latency: 2, 3 programmable wrap sequence: sequential or interleave automatic and controlled precharge command programmable burst length: 1, 2, 4, 8 and full page data mask for byte control auto refresh (cbr) 4096 refresh cycles / 64ms very low self refresh current power down and clock suspend mode random column address every clk (1-n rule) 54-fbga , with 9 x 6 ball array with 3 depopulated rows, 9 x 8 mm operating temperature range commerical (0 0 to 70 0 c) -7.5 -8 units f ck,max 133 125 mhz t ck3,min 7.5 8 ns t ac3,max 5.4 6 ns t ck2,min 9.5 9.5 ns t ac2,max 66ns 128-mbit synchronous low-power dram datasheet (rev. 2003-02)

hyb 39l128160ac/t 128-mbit 3.3v mobile-ram infineon technologies 10 2003-02 3rzhu2qdqg,qlwldol]dwlrq the default power on state of the mode register is supplier specific and may be undefined. the following power on and initialization sequence guarantees the device is preconditioned to each users specific needs. like a conventional dram, the synchronous dram must be powered up and initialized in a predefined manner. 9 dd must be applied before or at the same time as 9 ddq to the specified voltage when the input signals are held in the ? nop ? or ? deselect ? state. the power on voltage must not exceed 9 dd + 0.3 v on any of the input pins or vdd supplies. the clk signal must be started at the same time. after power on, an initial pause of 200 s is required followed by a precharge of all banks using the precharge command. to prevent data contention on the dq bus during power on, it is required that the dqm and cke pins be held high during the initial pause period. once all banks have been precharged, the mode register set command must be issued to initialize the mode register. a minimum of eight auto refresh cycles (cbr) are also required.these may be done before or after programming the mode register. failure to follow these steps may lead to unpredictable start-up modes. 3urjudpplqjwkh0rgh5hjlvwhu the mode register designates the operation mode at the read or write cycle. this register is divided into 4fields. a burst length field to set the length of the burst, an addressing selection bit to program the column access sequence in a burst cycle (interleaved or sequential), and a cas latency field to set the access time at clock cycle, an the mode set operation must be done before any activate command after the initial power up. any content of the mode register can be altered by re-executing the mode set command. all banks must be in precharged state and cke must be high at least one clock before the mode set operation. after the mode register is set, a standby or nop command is required. low signals of ras , cas , and we at the positive edge of the clock activate the mode set operation. address input data at this timing defines parameters to be set as shown in the previous table. ba0 and ba1 have to be set to ? 0 ? to enter the mode register. 5hdgdqg:ulwh2shudwlrq when ras is low and both cas and we are high at the positive edge of the clock, a ras cycle starts. according to address data, a word line of the selected bank is activated and all of sense amplifiers associated to the wordline are set. a cas cycle is triggered by setting ras high and cas low at a clock timing after a necessary delay, w rcd , from the ras timing. we is used to define either a read (we = h) or a write (we = l) at this stage. sdram provides a wide variety of fast access modes. in a single cas cycle, serial data read or write operations are allowed at up to a 133 mhz data rate. the numbers of serial data bits are the burst length programmed at the mode set operation, i.e., one of 1, 2, 4, 8 and full page. column addresses are segmented by the burst length and serial data accesses are done within this boundary. the first column address to be accessed is supplied at the cas timing and the subsequent addresses are generated automatically by the programmed burst length and its sequence. for example, in a burst length of 8 with interleave sequence, if the first address is ? 2 ? , then the rest of the burst sequence is 3, 0, 1, 6, 7, 4, and 5. full page burst operation is only possible using the sequential burst type and page length is a function of the i/o organisation and column addressing. full page burst operation does not self terminate once the burst length has been reached. in other words, unlike burst length of 2, 4 and 8, full page burst continues until it is terminated using another command.
hyb 39l128160ac/t 128-mbit 3.3v mobile-ram infineon technologies 11 2003-02 similar to the page mode of conventional dram ? s, burst read or write accesses on any column address are possible once the ras cycle latches the sense amplifiers. the maximum w ras or the refresh interval time limits the number of random column accesses. a new burst access can be done even before the previous burst ends. the interrupt operation at every clock cycle is supported. when the previous burst is interrupted, the remaining addresses are overridden by the new address with the full burst length. an interrupt which accompanies an operation change from a read to a write is possible by exploiting dqm to avoid bus contention. when two or more banks are activated sequentially, interleaved bank read or write operations are possible. with the programmed burst length, alternate access and precharge operations on two or more banks can realize fast serial data access modes among many different pages. once two or more banks are activated, column to column interleave operation can be performed between different pages. when the partial array activation is set, data will get lost when self-refresh is used in all non activated banks. 5hiuhvk0rgh mobile-ram has two refresh modes, auto refresh and self refresh. $xwr5hiuhvk auto refresh is similar to the cas -before-ras refresh of earlier drams. all banks must be precharged before applying any refresh mode. an on-chip address counter increments the word and the bank addresses. no bank information is required for both refresh modes. burst length and sequence burst length starting address (a2 a1 a0) sequential burst addressing (decimal) interleave burst addressing (decimal) 2xx0 xx1 0, 1 1, 0 0, 1 1, 0 4x00 x01 x10 x11 0, 1, 2, 3 1, 2, 3, 0 2, 3, 0, 1 3, 0, 1, 2 0, 1, 2, 3 1, 0, 3, 2 2, 3, 0, 1 3, 2, 1, 0 8 000 001 010 011 100 101 110 111 0 1 2 3 4 5 6 7 1 2 3 4 5 6 7 0 2 3 4 5 6 7 0 1 3 4 5 6 7 0 1 2 4 5 6 7 0 1 2 3 5 6 7 0 1 2 3 4 6 7 0 1 2 3 4 5 7 0 1 2 3 4 5 6 0 1 2 3 4 5 6 7 1 0 3 2 5 4 7 6 2 3 0 1 6 7 4 5 3 2 1 0 7 6 5 4 4 5 6 7 0 1 2 3 5 4 7 6 1 0 3 2 6 7 4 5 2 3 0 1 7 6 5 4 3 2 1 0 full page nnn cn, cn+1, cn+2 not supported
hyb 39l128160ac/t 128-mbit 3.3v mobile-ram infineon technologies 12 2003-02 the chip enters the auto refresh mode, when ras and cas are held low and cke and we are held high at a clock edge. the mode restores word line after the refresh and no external precharge command is necessary. a minimum w rc time is required between two automatic refreshes in a burst refresh mode. the same rule applies to any access command after the automatic refresh operation. in auto-refresh mode all banks are refreshed, independendly of the fact that the partial array self- refresh has been set or not. 6hoi5hiuhvk the chip has an on-chip timer that is used when the self refresh mode is entered. the self-refresh command is asserted with ras , cas , and cke low and we high at a clock edge. all external control signals including the clock are disabled. returning cke to high enables the clock and initiates the refresh exit operation. after the exit command, at least one w rc delay is required prior to any access command. '40)xqfwlrq dqmx has two functions for data i/o read and write operations. during reads, when it turns to ? high ? at a clock edge, data outputs are disabled and become high impedance after two clock periods (dqm data disable latency w dqz ). it also provides a data mask function for writes. when dqm is activated, the write operation at the next clock is prohibited (dqm write mask latency w dqw = zero clocks). 6xvshqg0rgh during normal access, cke is held high enabling the clock. when cke is low, it freezes the internal clock and extends data read and write operations. one clock delay is required for mode entry and exit (clock suspend latency t csl ). 3rzhu'rzq in order to reduce standby power consumption, a power down mode is available. all banks must be precharged before the mobile-ram can enter the power down mode. once the power down mode is initiated by holding cke low, all receiver circuits except for clk and cke are gated off. the power down mode does not perform any refresh operations, therefore the device can ? t remain in power down mode longer than the refresh period ( w ref ) of the device. exit from this mode is performed by taking cke ? high ? . one clock delay is required for power down mode entry and exit. $xwr3uhfkdujh two methods are available to precharge mobile-rams. in an automatic precharge mode, the cas timing accepts one extra address, ca10, to determine whether the chip restores or not after the operation. if ca10 is high when a read command is issued, the read with auto-precharge function is initiated. if ca10 is high when a write command is issued, the write with auto-precharge function is initiated. the mobile-ram automatically enters the precharge operation after w wr (write recovery time) following the last data in.
hyb 39l128160ac/t 128-mbit 3.3v mobile-ram infineon technologies 13 2003-02 3uhfkdujh&rppdqg there is also a separate precharge command available. when ras and we are low and cas is high at a clock edge, it triggers the precharge operation. three address bits, ba0, ba1 and a10 are used to define banks as shown in the following list. the precharge command can be imposed one clock before the last data out for cas latency = 2 and two clocks before the last data out for cas latency = 3. writes require a time delay w wr from the last data out to apply the precharge command. %dqn6hohfwlrqe\$gguhvv%lwv %xuvw7huplqdwlrq once a burst read or write operation has been initiated, there are several methods used to terminate the burst operation prematurely. these methods include using another read or write command to interrupt an existing burst operation, using a precharge command to interrupt a burst cycle and close the active bank, or using the burst stop command to terminate the existing burst operation but leave the bank open for future read or write commands to the same page of the active bank. when interrupting a burst with another read or write command care must be taken to avoid dq contention. the burst stop command, however, has the fewest restrictions making it the easiest method to use when terminating a burst operation before it has been completed. if a burst stop command is issued during a burst write operation, then any residual data from the burst write cycle will be ignored. data that is presented on the dq pins before the burst stop command is registered will be written to the memory. a10 ba0 ba1 0 0 0 bank 0 0 0 1 bank 1 0 1 0 bank 2 0 1 1 bank 3 1 x x all banks
