Abstract
A semiconductor storage apparatus includes a memory cell array including a plurality of memory string structures each including a pair of memory string formation sections each formed by a channel formation film and a charge storage film and including a select gate transistor and a plurality of memory cell transistors connected in series and a partial conductive layer configured to electrically connect the memory string formation sections. During a reading operation of a memory cell transistor, at least one of the plurality of memory cell transistors and the select gate transistor belonging to the memory string formation section is turned off such that a channel of a memory cell transistor is fixed to a potential of a source line or a potential of bit lines.
