Working Principles

The IDT7164L35Y is a static RAM chip that stores digital data using flip-flops. It operates by latching the input data onto internal memory cells when the write enable (WE) signal is active. The stored data can be accessed by providing the appropriate address on the address inputs (A0-A7) and activating the chip enable (CE) and output enable (OE) signals. The chip responds by placing the requested data on the data input/output pins (I/O0-I/O7).
