QDR II SRAM at 300 MHz — bus architecture note
The Cypress CY7C1515JV18-300BZXC is a 72Mbit synchronous SRAM built on the QDR II architecture — separate read and write data ports on independent buses, each clocked at 300 MHz. That eliminates the bus-turnaround dead cycles you get with common I/O SRAM, so back-to-back read-write throughput stays at the full 300 MHz rate. Organized as 2M x 36, it targets high-bandwidth data buffers in network switches, line cards, and test equipment where latency consistency matters more than raw density.
