General Description

The A43L0632 is 33,554,432 bits synchronous high data rate Dynamic RAM organized as 2 X 524,288 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.
