Abstract
To reduce a time required for verify processing of a semiconductor storage device, a semiconductor storage device according to one embodiment includes a plurality of unit memory arrays each including a plurality of memory blocks, a sense amplifier, and a verify circuit. When the semiconductor storage device performs verify processing, a pulse corresponding to verify data is applied to each memory cell of each memory block, and an expectation value corresponding to the verify data is set to each verify circuit. Each verify circuit performs the verify processing by comparing data stored read by the sense amplifier with the expectation value.
