It provides two independent ports with separate address, data, and control lines, allowing simultaneous read/write access from two bus masters without arbitration overhead. The 9 ns access time and 67 MHz clock frequency support back-to-back pipelined transactions, making it suited for shared-memory buffers in telecom line cards, packet processors, or FPGA bridging where the bus-turnaround penalty of asynchronous dual-port RAM would limit throughput.","metaTitle":"Infineon CY7C09389V-9AXCT SRAM Dual-Port Sync 64Kx18 9ns","metaDescription":"CY7C09389V-9AXCT obsolete dual-port synchronous SRAM, 1.152Mbit, 9ns access, 67MHz, 3V-3.6V, 100-TQFP.
