HM 65797

256 K x 1 High Speed CMOS SRAM

Introduction

The HM 65797 is a high speed CMOS static RAM

organized as 262, 144

1 bit. It is manufactured using

MHS high performance CMOS technology.

Access times as fast 20ns are available with maximum

power consumption of only 770 mW.

The HM 65797 features fully static operation requiring no

external clocks or timing strobes. The automatic

power-down feature reduces the power consumption by

67 % when the circuit is deselected.

Easy memory expansion is provided by an active low chip

select (CS) and three state drivers.

All inputs and outputs of the HM 65797 are TTL

compatible and operate from single 5 V supply thus

simplifying system design.

The HM 65797 is 100 % processed following the test

methods of MIL STD 883 and/or ESA/SCC 9000 making

it ideally suitable for military/space applications that

demand superior levels of performance and reliability.
