CMOS DYNAMIC RAM
Description
Features
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.

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 t CWD >= t CWD (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.
Rev 0.1 / Apr’01
GM71V17400C
GM71VS17400CL
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.
