QDR II SRAM at 250 MHz — what it means for the bus
The CY7C1515KV18-250BZXI from Cypress (now Infineon) is a 72 Mbit QDR II synchronous SRAM organized as 2M x 36 bits. The 250 MHz clock rate, combined with the QDR II architecture's separate read and write ports, delivers sustained bandwidth suitable for high-throughput applications like network packet buffers, ASIC cache, and FPGA-based signal processing. The 36-bit word width matches wide data buses without external byte-lane muxing, saving board space and latency.
