A floating gate(220) is formed on an upper portion of the gate dielectric. Electric field of the floating gate is constantly formed on the region overlapped with the source region. A control gate(250) is formed to be insulated from an upper portion of the floating gate along a sidewall of the floating gate. An intergate dielectric is disposed between the floating gate and the control gate. A drain region(270) is formed in the proximity of the other side of the control gate. A side of the floating gate adjacent to the source region has a curvature smaller than the other side of the floating gate.
