Abstract
A non-volatile memory device having a plurality of memory cells and a control circuit. The control circuit receives operation commands from outside the device and controls the operation of the device according to the commands. The commands include read commands and write commands. In the read command the control circuit reads data in the memory cells and outputs it. In a write command the control circuit controls the inputting of data to data latch circuits and then to memory cells. The control circuit provides status information indicating whether the writing of data is a success or a failure.
