The 71V3559 3.3V CMOS Synchronous SRAM is organized as 256K x 18. 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 71V3559 contains address, data-in and control signal registers. The outputs are flow-through (no output data register).
