ABSTRACT:
According to one embodiment, a semiconductor memory device can be generally characterized as including a gate insulating layer on a semiconductor substrate, a floating gate on the gate insulating layer and a word line disposed on one side of the floating gate. A first side of the floating gate facing the word line may include a projecting portion projecting toward the word line. A tip of the projecting portion may include a corner that extends substantially perpendicularly with respect to a top surface of the semiconductor substrate.
