GS8640ZV18/36T-300/250/200/167 72Mb Pipelined and Flow Through Synchronous NBT SRAM is a 72Mbit synchronous static SRAM launched by GSI Technology.
The GS8640ZV18/36T is a 72‑Mb synchronous static RAM (NBT SRAM) that supports both pipelined and flow‑through modes. It is offered in a 100‑pin TQFP package, operates from a 1.8 V core supply, and provides up to 300 MHz pipeline speed with 167 ns latency in flow‑through mode. Features include byte‑write capability, configurable pipeline/flow‑through operation, and automatic power‑down control.
The device is available in several density and speed options (e.g., 300 MHz/5.5 ns, 250 MHz/6.5 ns, 200 MHz/7.5 ns, 167 MHz/8 ns) and can be ordered with tape‑and‑reel packaging by appending “T” to the part number. Detailed pin descriptions, functional block diagrams, timing tables, and state diagrams are provided for design integration.
