Abstract
An electrically erasable programmable read-only memory cell array has a plurality of memory cells supplied with a supply voltage and a ground voltage. Each memory cell has a storage transistor with a floating gate. For each of selected memory cells, a first voltage higher than both the supply voltage and the ground voltage is applied to the control gate of the storage transistor and a second voltage lower than both the supply voltage and the ground voltage is applied to one of the source/drain electrodes of the storage transistor to thereby erase data in all of the selected memory cells.
