ABSTRACT:
A flash memory includes a memory sector, a command interface, a first signal buffer, a control signal generation circuit, a data input buffer, an error correction circuit, an address buffer, an address signal generation circuit, a plurality of data memory circuits, and write circuit. The command interface receives a write data input instruction from an external device to generate a write data input instruction signal, and receives a write instruction from the external device to generate a write instruction signal. The error correction circuit is activated by the write data input instruction signal to receive the write data in synchronization with the write enable signal, and is activated by the write instruction signal to generate a check data for an error correction in synchronization with the control signal.
