tm TE CH T2316162A DRAM FEATURES * Industry-standard x 16 pinouts and timing functions. * Single 5V (10%) power supply. * All device pins are TTL- compatible. * 1K-cycle refresh in 16ms. * Refresh modes: RAS only, CAS BEFORE RAS (CBR) and HIDDEN. * Extended data-out (EDO) PAGE MODE access cycle. * BYTE WRITE and BYTE READ access cycles. 1024K x 16 DYNAMIC RAM EDO PAGE MODE GENERAL DESCRIPTION The T2316162A is a randomly accessed solid state memory containing 16,777,216 bits organized in a x16 configuration. The T2316162A has both BYTE WRITE and WORD WRITE access cycles via two CAS pins. It offers Fast Page mode with Extended Data Output. The T2316162A CAS function and timing are determined by the first CAS to transition low and by the last to transition back high. Use only one of the two CAS and leave the other staying high during WRITE will result in a BYTE WRITE. CASL transiting low in a WRITE cycle will write data into the lower byte (DQ0~DQ7), and CASH transiting low will write data into the upper byte (DQ8~DQ15).

Publication Date:APR. 2002 Revision:E tm TE CH T2316162A 12. These parameters are referenced to CAS leading edge in EARLY WRITE cycles and WE leading edge in LATE WRITE or READMODIFY-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-MODIFY-WRITE operation is not possible. 14. 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. 15. WRITE command is defined as WE going low. 16. 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. 17. The I/Os open during READ cycles once tOFF1 or tOFF2 occur. 18. The first CAS edge to transition low. 19. The last CAS edge to transition high. 20. Output parameter (I/O) is referenced to corresponding CAS input, IO1~8 by CASL and IO9~16 by CASH . 21. Last falling CAS edge to first rising CAS edge. 22. Last rising CAS edge to next cycle's last rising CAS edge. 23. Last rising CAS edge to first falling CAS edge. 24. First IOs controlled by the first CAS to go low. 25. Last IOs controlled by the last CAS to go high. 26. Each CAS must meet minimum pulse width. 27. Last CAS to go low. 28. All IOs controlled, regardless CASL and CASH . 29. Data outputs are measured with a load of 50pF. The output reference levels are VOH/VOL =2.0V/0.8V; The input levels are VIH/VIL= 3.0V/0V. Notes: 1. Enables on-chip refresh and address counters. 2. VIH(2.4V) and VIL(0.8V) are reference levels for measuring timing of input signals. Transition times are measured between VIH (2.4V) and VIL (0.8V). 3. In addition to meet the transition rate specification, all input signals must transit between VIH and VIL in a monotonic manner. 4. 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. 5. Assume that tRCD tRCD(max) . 6. 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. 7. Operation within the tRCD(max) limit ensures that tRAC(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. 8. Operation within the tRAD limit ensures that tRAC(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. 9. Either tRCH or tRRH must be satisfied for a READ cycle. 10. tOFF1(max) defines the time at which the output achieves the open circuit condition; it is not a reference to VOH or VOL. 11. tWCS, tRWD, tAWD and tCWD are restrictive operating parameters in LATE WRITE and READ-MODIFY-WRITE cycles 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 back to VIH) is indeterminate. OE held high and WE taken low after CAS goes low result in a LATE WRITE( OE controlled) cycle. TM Technology Inc. reserves the right P. 6 to change products or specifications without notice.
