General Description

The A45L9332A is 16,777,216 bits synchronous high data

rate Dynamic RAM organized as 2 X 262,144 words by 32

bits, fabricated with AMIC’s high performance CMOS

technology. Synchronous design allows precise cycle

control with the use of system clock. I/O transactions are

possible on every clock cycle. Range of operating

frequencies, programmable latencies allows the same

device to be useful for a variety of high bandwidth, high

performance memory system applications.

Write per bit and 8 columns block write improves

performance in graphics system.
