描述 Description

The 71V5463.3VCMOS SRAM is organized as 128K x 36 bits. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus it has been given the name ZBTTM, or Zero Bus Turn-around. The 71V546 contains data I/O, address and control signal registers. In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.
