... Functional Description The AS7C331MNTF18A family is a high performance CMOS 16 Mbit synchronous Static Random Access Memory (SRAM) organized as 1,048,576 words × 18 bits and incorporates a LATE Write. This variation of the 16Mb+ synchronous SRAM uses the No Turnaround Delay (NTD write operation that improves bandwidth over flowthrough burst devices normal flowthrough burst device, the write data, command, and address are all applied to the device on the same clock edge ...
