A semiconductor memory comprises: a first conductivity type semiconductor substrate and memory cells each constituted of an island-like semiconductor layer, a charge storage layer and a control gate, the charge storage layer and the control gate being formed to entirely or partially encircle a sidewall of the island-like semiconductor layer, wherein the memory cells are disposed in series, and the island-like semiconductor layer on which the memory cells are disposed has cross-sectional areas in a horizontal direction which vary stepwise.
