9-Mbit (256K X 32) Flow-Through Sync SRAM

The CY7C1365C is a 256K x 32 synchronous cache RAM designed to Interface with high-speed Microprocessors with minimum glue Logic Maximum access delay from Clock rise is 6.5 ns (133-MHz version). A 2-bit on-chip Counter captures the first address in a burst and increments the address automati- cally for the rest of the burst access. All synchronous inputs are gated by Registers controlled by a positive-edge-triggered Clock Input (CLK). The synchronous inputs include all addresses, all data inputs, address-pipelining Chip Enable [2] (CE1), depth-expansion Chip Enables (CE2 and CE3 ), Burst Control inputs (ADSC, ADSP, and ADV), Write Enables (BW[A:D], and BWE), and Global Write (GW). Asynchronous inputs include the Output Enable (OE) and the ZZ pin. By Cypress Semiconductor Corp.
