Semiconductor storage device

摘要

A device includes a cell array including cells. A sense node transmits logic of data stored in the cell selected by a WL and a BL. A verify read in a data program sequence includes a first read and a second read. In a time period of shifting from the first read to the second read, a charge state of the sense node is maintained.

1. A semiconductor storage device comprising:
a memory cell array comprising a plurality of memory cells; a plurality of word lines connected to control gates of the memory cells; a bit line electrically connectable to the memory cells; and a sense node transmitting logic of data stored in the memory cell selected by the word line and the bit line, wherein a verify read operation in a data program sequence comprises a first read operation and a second read operation, in a time period of shifting from the first read operation to the second read operation, a charge state of the sense node is maintained, and the sense node is not precharged between the first read operation and the second read operation.
