4,194,304 WORDS x 4 BIT CMOS DYNAMIC RAM
Description
The GM71V(S)17400C/CL is the new generation dynamic RAM organized 4,194,304 words x 4 bit. GM71V(S)17400C/CL has realized higher density, higher performance and various functions by utilizing advanced CMOS process technology. The GM71V(S)17400C/CL offers Fast Page Mode as a high speed access mode. Multiplexed address inputs permit the GM71V(S)17400C/CL to be packaged in a standard 300 mil 24(26) pin SOJ, and a standard 300 mil 24(26) pin plastic TSOP II. The package size provides high system bit densities and is compatible with widely available automated testing and insertion equipment. System oriented features include single power supply 3.3V+/-0.3V tolerance, direct interfacing capability with high performance logic families such as Schottky TTL.

GM71V17400C GM71VS17400CL
Notes: 1. AC Measurements assume tT =5ns. 2. An initial pause of 200us is required after power up followed by a minimum of eight initialization cycles (any combination of cycles containing RAS-only refresh or CAS-beforeRAS refresh). If the internal refresh counter is used, a minimum of eight CAS-before-RAS refresh cycles are required. 3. Operation with the tRCD(max) limit insures 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, then access time is controlled exclusively by tCAC. 4. Operation with the tRAD(max) limit insures 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, then access time is controlled exclusively by tAA. 5. Either tODD or tCDD must be satisfied. 6. Either tDZO or tDZC must be satisfied. 7. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Also, transition times are measured between VIH(min) and VIL(max). 8. Assume that tRCD<=tRCD(max) and tRAD<=tRAD(max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, tRAC exceeds the value shown. 9. Measured with a load circuit equivalent to 1 TTL loads and 100pF (VOH = 2.0V, VOL = 0.8V) 10. Assume that tRCD >=tRCD(max) and tRCD + tCAC(max) >= tRAD + tAA(max). 11. Assume that tRAD >=tRAD(max) and tRCD + tCAC(max) <= tRAD + tAA(max). 12. Either tRCH or tRRH must be satisfied for a read cycles. 13. tOFF(max) and tOEZ(max) define the time at which the outputs achieve the open circuit condition and are not referenced to output voltage levels. 14. tWCS, tRWD, tCWD, tAWD and tCPW are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only; if tWCS>=tWCS(min), the cycles is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if tRWD>=tRWD(min), tCWD>=tCWD(min), and tAWD>=tAWD(min), or tCWD>=tCWD(min), tAWD>= tAWD(min) and tCPW>=tCPW(min), the cycle is a read-modify-write and the data output will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, the condition of the data out (at access time) is indeterminate. 15. These parameters are referenced to CAS leading edge in early write cycles and to WE leading edge in delayed write or read-modify-write cycles. 16. tRASP defines RAS pulse width in Fast page mode cycles. 17. Access time is determined by the longest among tAA or tCAC or tACP.

18. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. After RAS is reset, if tOEH>=tCWL, the I/O pin will remain open circuit (high impedance); if tOEH < tCWL, invalid data will be out at each I/O. 19. The 16M DRAM offers a 16-bit time saving parallel test mode. Address CA0 and CA1 for the 4M x 4 are don't care during test mode. Test mode is set by performing a WE-and-CAS-beforeRAS (WCBR) cycle. In 16-bit parallel test mode, data is written into 4 bits in parallel at each I/O (I/O1 to I/O4) and read out from each I/O. If 4 bits of each I/O are equal (all 1s or 0s), data output pin is a high state during test mode read cycle, then the device has passed. If they are not equal, data output pin is a low state, then the device has failed. Refresh during test mode operation can be performed by normal read cycles or by WCBR refresh cycles. To get out of test mode and enter a normal operation mode, perform either a regular CAS-before-RAS refresh cycle or RAS-only refresh cycle. 20. In a test mode read cycle, the value of tRAC, tAA, tCAC and tACP is delayed by 2ns to 5ns for the specified value. These parameters should be specified in test mode cycles by adding the above value to the specified value in this data sheet.
