Working Principles

The CY7C1021B-15ZC operates based on the principles of static random access memory. It utilizes flip-flops to store and retrieve data. When an address is provided, the corresponding data is accessed from the memory array. The output buffers are controlled by the OE# pin, enabling the data to be read from or written to the chip. The WE# pin allows for write operations, while the CE# pins selectively enable or disable the chip for specific memory locations.
