Abstract
An electrically erasable and programmable non-volatile semiconductor memory device and method of erasing the same device are provided. A fail bit counter is provided for the device and method. The fail bit counter counts erase fail bits during the sector erase operation. An erase control circuit selectively terminates the sector erase operation depending upon erase fail bit number.
