Preliminary
Features
n Power supply range: 4.5V to 5.5V
n Access times: 70 ns (max.)
n Current:
n Full static operation, no clock or refreshing required
n All inputs and outputs are directly TTL compatible
General Description
The A627308 is a low operating current 1048,576-bit
static random access memory organized as 131,072
words by 8 bits and operates on a power supply voltage
from 4.5V to 5.5V.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
