The 71V3557 3.3V CMOS Synchronous SRAM is organized as 128K x 36. 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 Turnaround. The 71V3557 contains address, data-in and control signal registers. The outputs are flow-through (no output data register).
