説明

The 71V65703 3.3V CMOS SRAM, organized as 256K x 36, 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 ZBT™, or Zero Bus Turnaround. The 71V65703 contains address, data-in, and control signal registers. The outputs are flow-through (no output data register). In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.
