Electrically erasable memory matrix (EEPROM)

摘要

EEPROM showing storage cells comprising a tunnel injector which at the one hand is connected to a first bit line by means of the source-drain-line of a floating gate FET and at the other hand to a second bit line by means of the source-drain-line of a selection FET. Interferences between addressed groups and not addressed groups of storage cells during writing are eliminated by means of connection of the first bitline of the not addressed groups via the source-drain-lines of a depletion type FET and an enhancement FET to ground.
