Working Principles

The IDT7164L20TPI is a static RAM that stores digital information using flip-flops. It operates by storing data in a matrix of memory cells, each consisting of a flip-flop circuit. The stored data can be accessed and modified through the address and control inputs. The chip enable (CE), output enable (OE), and write enable (WE) inputs control the read and write operations. The data is transferred between the memory cells and the external system through the input/output (I/O) pins.
