Working Principles

The IDT7202LA25SOI8 is a synchronous SRAM that stores and retrieves data using an array of flip-flops. It operates based on clock signals, which synchronize the data transfer between the memory and the external system. When enabled, the chip reads or writes data from/to the specified memory location based on the address inputs. The output buffers are controlled by the output enable signal, allowing bidirectional data flow.
