  • Electrically erasable and programmable read only memory device with simple controller for selecting operational sequences after confirmation
    Patent number: 5295108
    Abstract: An electrically erasable and programmable read only memory device is responsive to an external command signal for selectively executing an erasing operation, a write-in operation and a verifying operation, and a controller is incorporated in the electrically erasable and programmable read only memory device for producing internal control signals from the external command signal, wherein the external command signal is split into higher order bits and lower order bits both indicative of the external command, and the controller compares the higher order bits with the lower order bits so as to exactly discriminate the external command.
