Working Principles

The MX25U25645GMI00 utilizes the Serial Peripheral Interface (SPI) to communicate with the host device. It stores data in non-volatile memory cells that can be electrically erased and programmed. When the host sends commands and addresses through the SPI interface, the chip retrieves or writes data from/to the memory array. The data is then transferred between the chip and the host using the serial data lines (SI and SO). The chip's internal circuitry manages the erase, program, and read operations, ensuring reliable data storage and retrieval.
