Abstract

According to one embodiment, memory includes a memory cell transistor including a floating gate electrode, a control gate electrode and a first inter-gate insulating film between floating gate and control gate electrodes, a field effect transistor including a lower electrode layer, an upper electrode layer, and a second inter-gate insulating film between the lower and upper electrode layers. The lower electrode layer having an n-type silicon film, the second inter-gate insulating film having a first opening, and the upper electrode layer having a p-type silicon film. The p-type silicon film is provided on the n-type silicon film via the first opening.
