The memory array utilizes Dual-Port memory cells to allow simultaneous access of any address from both ports. Registers on control, data, and address inputs provide minimal setup and hold times. The timing latitude provided by this approach allows systems to be designed with very short cycle times. With an input data register, the IDT70V9169/59 has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 450mW of power.

ADS = VIL, CNTEN and CNTRST = VIH. 4. The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL following the next rising edge of the clock. Refer to Truth Table 1. 5. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 6. "X' here denotes Left or Right port.

B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT70V916/59L for this waveform, and are setup for depth expansion in this example. ADDRESS(B1) = ADDRESS(B2) in this situation. 2. OE and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH. 3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 4. CE0 and ADS = VIL; CE1, CNTEN, and CNTRST = VIH. 5. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to. 6. If tCCS < maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD. If tCCS > maximum specified, then data from right port READ is not valid until tCCS + tCD1. tCWDD does not apply in this case. 7. All timing is the same for both Left and Right ports. Port "A" may be either Left or Right port. Port "B" is the opposite from Port "A". 6.42 10 IDT70V9169/59L High-Speed 3.3V 16/8K x 9 Dual-Port Synchronous Pipelined Static RAM Preliminary Industrial and Commercial Temperature Ranges Timing Waveform of Pipelined Read-to-Write-to-Read (OE = VIL)(3) tCYC2 tCH2 tCL2 CLK CE0 tSC CE1 tSW tHW R/W tSW tHW tHC ADDRESS (4) An tSA tHA An +1 An + 2 An + 2 tSD tHD Dn + 2 An + 3 An + 4 DATAIN (2) tCD2 Qn READ tCKHZ (1) tCKLZ (1) tCD2 Qn + 3 DATAOUT NOP (5) WRITE READ 5655 drw 11 Timing Waveform of Pipelined Read-to-Write-to-Read (OE Controlled)(3) tCH2 CLK CE0 tSC CE1 tSW tHW R/W tSW tHW tHC tCYC2 tCL2 ADDRESS (4) An tSA tHA An +1 An + 2 tSD tHD An + 3 An + 4 An + 5 DATAIN (2) tCD2 Qn tOHZ (1) Dn + 2 Dn + 3 tCKLZ(1) tCD2 Qn + 4 DATAOUT OE READ WRITE READ 5655 drw 12 NOTES: 1.

CE0 and R/W = VIL; CE1 and CNTRST = VIH. 2. CE0 = VIL; CE1 = VIH. 3. The "Internal Address" is equal to the "External Address" when ADS = VIL and equals the counter output when ADS = VIH. 4. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use only. 5. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals. 6. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset cycle. ADDR0 will be accessed. Extra cycles are shown here simply for clarification. 7. CNTEN = VIL advances Internal Address from `An' to `An +1'. The transition shown indicates the time required for the counter to advance. The `An +1' Address is written to during this cycle. 6.42 14 IDT70V9169/59L High-Speed 3.3V 16/8K x 9 Dual-Port Synchronous Pipelined Static RAM Preliminary Industrial and Commercial Temperature Ranges .unctional Description The IDT70V9169/59 provides a true synchronous Dual-Port Static RAM interface. Registered inputs provide minimal set-up and hold times on address, data, and all critical control inputs. All internal registers are clocked on the rising edge of the clock signal, however, the self-timed internal write pulse is independent of the LOW to HIGH transition of the clock signal. An asynchronous output enable is provided to ease asynchronous bus interfacing. Counter enable inputs are also provided to stall the operation of the address counters for fast interleaved memory applications. CE0 = VIL and CE1 = VIH for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT70V9169/59's for depth expansion configurations. When the Pipelined output mode is enabled, two cycles are required with CE0 = VIL and CE1 = VIH to re-activate the outputs. Depth and Width Expansion The IDT70V9169/59 features dual chip enables (refer to Truth Table I) in order to facilitate rapid and simple depth expansion with no requirements for external logic. Figure 4 illustrates how to control the varioius chip enables in order to expand two devices in depth. The IDT70V9169/59 can also be used in applications requiring expanded width, as indicated in Figure 4. Since the banks are allocated at the discretion of the user, the external controller can be set up to drive the input signals for the various devices as required to allow for 36-bit or wider applications.
