What this dual-port SRAM does
The Infineon CY7C024AV-25AC is a 64Kbit dual-port asynchronous SRAM organized as 4K x 16 bits. It gives two independent bus masters simultaneous read/write access to the same memory array through separate address, data, and control ports — no arbitration logic needed on the board. The 25 ns access time means each port can complete a read or write cycle within 25 ns, which sets the timing margin for shared-memory handshaking in multiprocessor or FIFO-like data buffers.
It is better suited for asynchronous handshake or wait-state insertion.
