General Description
The A43L3616 is 134,217,728 bits synchronous high data
rate Dynamic RAM organized as 4 X 2,097,152 words by
16 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.
