Functional Description
The Cypress Synchronous Burst SRAM family employs high-speed, low-power CMOS designs using advanced triple-layer polysilicon, double-layer metal technology. Each memory cell consists of four transistors and two high valued resistors.
The CY7C1340A/GVT71128C32 SRAM integrates 131,072 × 32 SRAM cells with advanced synchronous peripheral circuitry and a two-bit counter for internal burst operation.
