Functional Description
The CY7C1300A SRAM integrates 131,072 × 36 SRAM cells with advanced synchronous peripheral circuitry. It 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 CY7C1300A allows the user to concurrently perform Reads, Writes, or pass-through cycles in combination on the two data ports. The two address ports (AX, AY) determine the Read or Write locations for their respective data ports (DQX, DQY).
