GENERAL DESCRIPTION
The M10B416256A is a randomly accessed solid state memory, organized as 262,144 x 16 bits device. It offers FAST Page Mode, 5V( 10%) single power supply. Access time (-50, -60) and package type (SOJ, TSOP II) are optional features of this family. All these family have CAS - before - RAS , RAS -only refresh and Hidden refresh capabilities. Two access modes are supported by this device : Byte access and Word access. Use only one of the two CAS and leave the other staying high will result in a BYTE access. WORD access happens when two CAS ( CASL , CASH ) are used. CASL transiting low during READ or WRITE cycle will output or input data into the lower byte (IO0~IO7), and CASH transiting low will output or input data into the upper byte (IO8~15).

Notes : 1. 2. Enables on-chip refresh and address counters. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Transition times are measured between VIH and VIL. In addition to meet the transition rate specification, all input signals must transit between VIH and VIL in a monotonic manner. Assume that tRCD < tRCD(max). If tRCD is greater than the maximum recommended value shown in this table, tRAC will increase by the amount that tRCD exceeds the value shown. Assume that tRCD tRCD (max) If CAS is low at the falling edge of RAS , data-out will be maintained from the previous cycle. To initiate a new cycle and clear the data-out buffer, CAS and
RAS must be pulsed high.

back to VIH ) is indeterminate. OE held high and WE taken low after CAS goes low result in a LATE WRITE ( OE -controlled) cycle. 12. Those parameters are referenced to CAS leading edge in EARLY WRITE cycles and WE leading edge in LATE WRITE or READ-MODIFY- WRITE cycles. 13. During a READ cycle, if OE is low then taken HIGH before CAS goes high, I/O goes open, if OE is tied permanently low, a LATE WRITE or READ-MODIFYWRITE operation is not possible. An initial pause of 100ms is required after power-up followed by eight RAS refresh cycles ( RAS only or CBR) before proper device operation is assured. The eight RAS cycle wake-ups should be repeated any time the tREF refresh requirement is exceeded. WRITE command is defined as WE going low. LATE WRITE and READ-MODIFY-WRITE cycles must have both tOFF2 and tOEH met ( OE high during WRITE cycle) in order to ensure that the output buffers will be open during the WRITE cycles. The I/Os open during READ cycles once tOFF1 or tOFF2 occur. Referenced to the earlier CAS falling edge.

Operation within the tRCD limit ensures that tRCD (max) can be met, tRCD (max) is specified as a reference point only ; if tRCD is greater than the specified tRCD (max) limit, access time is controlled by tCAC. Operation within the tRAD limit ensures that tRAD(max) can be met. tRAD(max) is specified as a reference point only ; if tRAD is greater than the specified tRAD (max) limit, access time is controlled by tAA. Either tRCH or tRRH must be satisfied for a READ cycle. tOFF1(max) defines the time at which the output achieves the open circuit condition ; it is not a reference to VOH or VOL. tWCS, tRWD, tAWD and tCWD are restrictive operating parameters in LATE WRITE and READ-MODIFYWRITE cycle only. If tWCS tWCS(min) , the cycle is an EARLY WRITE cycle and the data output will remain an open circuit throughout the entire cycle. If tRWD tRWD(min) , tAWD tAWD(min) and tCWD tCWD(min) , the cycle is READ-WRITE and the data output will contain data read from the selected cell. If neither of the above conditions is met, the state of I/O (at access time and until CAS and RAS or OE go

Note : 1. tRSR and tRHR are for system design reference only. The WE signal is actually a "don' t care" at RAS time during a CBR REFRESH. However, WE should be held HIGH at RAS time during a CBR REFRESH to ensure compatibility with other DRAMs which require WE HIGH at RAS time during a CBR REFRESH.
