ABSTRACT:
A semiconductor memory device comprises a memory cell unit including at least one memory cell having a structure with a floating gate and a control gate stacked via an insulator on a semiconductor substrate. A common source line is connected to one end of the memory cell unit. A bit line is connected to the other end of the memory cell unit. The control gate has at least an upper portion with a width along the gate length formed wider than the width of the floating gate.
