QDR-II SRAM at 167 MHz — what the clock rate buys you
The CY7C1412BV18-167BZC is a 36 Mbit synchronous QDR-II SRAM from Cypress, organized 2M x 18 and clocked at 167 MHz. That clock rate defines the peak read/write throughput on the parallel bus — at 167 MHz the QDR-II architecture delivers two data words per clock cycle on separate read and write ports, so the effective bandwidth is double what a conventional synchronous SRAM at the same frequency would provide. For designs that need sustained back-to-back transactions without dead cycles — think network packet buffers, test-equipment waveform memories, or high-speed data acquisition — this part eliminates the bus-turnaround penalty of a common I/O SRAM.
