FEATURES

DESCRIPTION

The ISSI IS61C256AH is a very high-speed, low power,

32,768 word by 8-bit static RAMs. They are fabricated using

ISSI's high-performance CMOS technology. This highly reli-

able process coupled with innovative circuit design tech-

niques, yields access times as fast as 10 ns maximum.

• High-speed access time: 10, 12, 15, 20, 25 ns

• Low active power: 400 mW (typical)

• Low standby power

— 250 µW (typical) CMOS standby

— 55 mW (typical) TTL standby

WhenCEisHIGH(deselected), thedeviceassumesastandby

mode at which the power dissipation can be reduced down to

250 µW (typical) with CMOS input levels.

• Fully static operation: no clock or refresh

required

• TTL compatible inputs and outputs

• Single 5V power supply

Easy memory expansion is provided by using an active LOW

ChipEnable(CE)inputandanactiveLOWOutputEnable(OE)

input. The active LOW Write Enable (WE) controls both writing

and reading of the memory.

The IS61C256AH is pin compatible with other 32K x 8 SRAMs

and are available in 28-pin PDIP, SOJ, and TSOP (Type I)

packages.
