1,048,576 WORDS x 4BIT
CMOS DYNAMIC RAM
Description
Features
The GM71C(S)4400C/CL is the new generation
dynamic RAM organized 1,048,576 words x 4 bit.
GM71C(S)4400C/CL has realized higher density,
higher performance and various functions by
utilizing advanced CMOS process technology. The
GM71C(S)4400C/CL offers Fast Page Mode as a
high speed access Mode. Multiplexed address
inputs permit the GM71C(S)4400C/CL to be
packaged in a standard 300mil 20(26) pin plastic
SOJ and standard 300mil 20(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 of 5V+/-10% tolerance, direct
interfacing capability with high performance logic
families such as Schottky TTL.

Notes:
1. AC Measurements assume tT = 5ns.
2. Assumes 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.
3. Measured with a load circuit equivalent to 2TTL loads and 100§Ü.
4. Assumes that tRCD>=tRCD(max) and tRAD<=tRAD(max).
5. Assumes that tRCD<=tRCD(max) and tRAD>=tRAD(max).
6. tOFF(max) defines the time at which the output achieves the open circuit condition and is not
referenced to output voltage levels.
7. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Also,
transition times are measured between VIH and VIL.
8. 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.
9. 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.

10. tWCS, tRWD, tCWD tCPW and tAWD are not restrictive operating 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 impedance) throughout the entire cycle; if
tRWD>=tRWD(min), tCWD>=tCWD(min), tAWD>=tAWD(min) and tCPW>=tCPW(min), the cycle is a readmodify-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.
11. These parameters are referenced to CAS leading edge in early write cycles and to WE leading
edge in delayed write or a read modify write cycle.
12. tRASP defines RAS pulse width in fast page mode cycles.
13. Access time is determined by the longer of tAA or tCAC or tACP.
14. An initial pause of 100us is required after power up followed by a minimum of eight
initialization cycles (RAS only refresh cycle or CAS before RAS refresh cycle). If the internal
refresh counter is used, a minimum of eight CAS before RAS refresh cycles is required.
15. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying
data to the device.
16. Test mode operation specified in this data sheet is 2-bit test function controlled by control
address bits - - - CA0. This test mode operation can be performed by WE-and-CAS-before-RAS
(WCBR) refresh cycle. Refresh during test mode operation will be performed by normal read
cycles or by WCBR refresh cycles. When the state of two test bits accord each other, the
condition of the output data is low level. In order to end this test mode operation, perform a RAS
only refresh cycle or a CAS-before-RAS refresh cycle.
17. In a test mode read cycle, the value of tRAC, tAA, tCAC, tOAC and tACP is delayed for 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.
