Working Principles

The IDT7201LA25SO is a synchronous SRAM that stores and retrieves data using an internal clock signal. When the chip enable (CE) pins are activated, the address inputs (A0-A17) specify the location where data is to be read from or written to. The write enable (WE) pin controls the writing of data, while the output enable (OE) pin enables the data outputs. The byte enable (UB/LB) pins allow for selective reading or writing of individual bytes within a word.
