GM71VS16163CL
1,048,576 WORDS x 16 BIT
CMOS DYNAMIC RAM
Description
Features
The GM71V(S)16163C/CL is the new generation
dynamic RAM organized 1,048,576 x 16 bit.
GM71V(S)16163C/CL has realized higher density,
higher performance and various functions by utilizing
advanced CMOS process technology. The
GM71V(S)16163C/CL offers Extended Data
out(EDO) Mode as a high speed access mode.
Multplexed address inputs permit the
GM71V(S)16163C/CL to be packaged in standard
400 mil 42pin plastic SOJ, and standard 400mil
44(50)pin plastic TSOP II. The package size provides
high system bit densities and is compatible with
widely available automated testing and insertion
equipment.
* 1,048,576 Words x 16 Bit Organization
* Extended Data Out Mode Capability
* Single Power Supply (3.3V+/-0.3V)
* Fast Access Time & Cycle Time

2. tWCS >= 0ns

3. Mode is determined by the OR fuction of the UCAS and LCAS. (Mode is set by earliest of
UCAS and LCAS active edge and reset by the latest of UCAS and LCAS inactive edgs.) However
write OPERATION and output HIZ control are done independently by each UACS,LCAS.
ex. if RAS = H to L, UCAS = H, LCAS = L, then CAS-before-RAS refresh cycle is selected.

Notes:
1. AC measurements assume tT = 5ns.
2. An intial pause of 200us is required after power up followd by a minimum of eight initialization
cycles(any combination of cycles containing RAS-only refresh or CAS-before-RAS 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 >= tRAD(max) + tAA(max) - tCAC(max), 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 tOED 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. Assumes that tRCD <= tRCD(max) and tRAD <= tRAD(max). If tRCD ot 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 load and 100pF.
10. Assumes that tRCD >= tRCD(max) and tRCD + tCAC(max) >= tRAD + tAA(max).
11. Assumes 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 referred to output voltage levels.
14. tWCS, tRWD, tCWD, tAWD and tCPW are not restrictive operationg parameters. They are included in
the data sheet as electrical characteristics only; if tWCS >= tWCS(min), the cycle is an early write
cycle and the data out pin will remain open circuit (high impedence) 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 data out (at access time)is indeterminate.
15. These parameters are referred to UCAS and LCAS 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 EDO page mode cycles.
17. Access time is determined by the longest among tAA,tCAC,and 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 impedence); if tOEH< tCWL, invalid data will be out at each I/O.
19. When both UCAS and LCAS go low at the same time, all 16-bit data are written into the device.
UCAS and LCAS cannot be staggered within the same write/read cycles.
20. All the VCC and VSS pins shall be supplied with the same voltages.

21. tASC, tCAH, tRCS, tWCS,tWCH,tCSR and tRPC are determined by the earlier falling edge of UCAS
or LCAS.
22. tCRP,tCHR, tRCH, tACP and tCPW are determned by the later rising edge of UCAS or LCAS.
23. tCWL, tDH,tDS and tCSH should be satisfied by both UCAS and LCAS.
24. tCP is determined by that time the both UCAS and LCAS are high.
25. When output buffers are enabled once, sustain the low impedence state until valid data is
obtained.
When output buffer is turned on and off within a very short time, generally it causes large
VCC/VSS line noise, which causes to degrade VIH min/VIL max level.
26. Please do not use tRASS timing, 10us <= tRASS <=100us. During this period, the device is in
transition state from normal operation mode to self refresh mode. If tRASS >=100us, then
RAS precharge time should use tRPS instead of tRP.
27. If you use distributed CBR refresh within 15.6us inteval in normal read/write cycle, CBR
refresh should be executed within 15.6us immediately after exiting from and before entering
into self refresh mode.
28. If you use RAS only refresh or CBR burst refresh mode in normal read/write cycle,4096 or
1024 cycles of distributed CBR refresh with 15.6us interval should be executed within 64 or
16ms immediately after exiting from and before entering into the self refresh mode.
29. Repetitive self refresh mode without refreshing all memory is not allowed. Once you exit from
self refresh mode, all memory cells need to be refreshed before re-entering the self refresh mode
again.
30. H or L (H: VIH(min) <= VIN <= VIH(max), L: VIL(min) <= VIN <= VIL(max))

Notes concerning 2CAS control
Please do not separate the UCAS / LCAS operation timing intentionally. However skew between
UCAS / LCAS are allowed under the following conditions.
1. Each of the UCAS / LCAS should satisfy the timing specifications individually.
2. Different operation mode for upper/lower byte is not allowed;such as following.
RAS
Delayed write
UCAS
Early write
LCAS
WE
3. Closely separated upper/lower byte control is not allowed. However when the condition
(tcp < tUL)is satisfied,EDO page mode can be performed.
RAS
UCAS
LCAS
tUL
4. Byte control operation by remaining UCAS or LCAS high is guaranteed.
