GENERAL DESCRIPTION
The AS6C8008A families are fabricated by Alliance
Memory’s advanced full CMOS process technology.
The families support industrial temperature range
and Chip Scale Package for user flexibility of system design.
The families also supports low data retention voltage
for battery back- up operation with low data retention
current.
Process Technology : 0.15 µm Full CMOS
Organization : 1M x 8 bit
Power Supply Voltage : 2.7V ~ 3.6V
Low Data Retention Voltage : 1.5V(Min.)
Three state output and TTL Compatible
Package Type : 48-FPBGA, 44-TSOP2

1. Stresses greater than those listed under “nav” may cause permanent damage to the device. Functional
operation should be restricted to recommended operating condition. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
