IDT71V3556S - 3.3V Synchronous ZBT SRAMs
The IDT71V3556/58 are 3.3V high-speed 4,718,592-bit (4.5 Megabit) synchronous SRAMS.
They are designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads.
Thus, they have been given the name ZBTTM, or Zero Bus Turnaround.
