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.
