Working Principles

The IDT71256SA25YI8 is a static random-access memory (SRAM) chip. It stores data using flip-flops, which retain their state as long as power is supplied. The chip uses an address bus to select the desired memory location and a data bus to read from or write to that location. The chip's control pins (CE, OE, and WE) enable or disable specific operations.
