What this QDR II SRAM brings to a high-throughput design
Organized as 1M x 36, it clocks at 250 MHz, giving a peak bandwidth that keeps a 10G packet buffer or a logic analyzer's trace memory fed without wait states. It runs from a 1.7V to 1.9V core supply, so you need a clean 1.8V rail — any droop below 1.7V risks data integrity. If your system lives in a controlled environment, this part fits cleanly.
At 250 MHz the QDR II interface delivers back-to-back transactions with zero idle cycles between read and write turns. That matters when the FPGA or ASIC on the other side of the bus is running a state machine that cannot stall. The 1M x 36 organization gives a 36-bit data word per access, which maps naturally to a 36-bit or 72-bit (two-chip) memory bus without packing overhead.
