HM 65797
256 K x 1 High Speed CMOS SRAM
Introduction
The HM 65797 is a high speed CMOS static RAM Easy memory expansion is provided by an active low chip
organized as 262, 144 × 1 bit. It is manufactured using select (CS) and three state drivers.
MHS high performance CMOS technology.
All inputs and outputs of the HM 65797 are TTL
Access times as fast 20ns are available with maximum compatible and operate from single 5 V supply thus
power consumption of only 770 mW.
