ABSTRACT:
A nonvolatile semiconductor memory includes: a memory sub array including a memory cell unit configured with a memory cell transistor and a select transistor connected in series; a control gate line driver including a control gate line driver transistor connected to a control gate line of the memory cell transistor; and a select transistor gate line driver including a select gate line driver transistor connected to a select gate line of the select transistor. A thickness of a gate insulator of the control gate line driver transistor is thicker than that of the select gate line driver transistor.
