Abstract
In one embodiment, a semiconductor storage device includes a string that has one end electrically connected to a bit line, and another end electrically connected to a source line, and includes a plurality of memory cells. An operation of writing data to each of a plurality of adjacent first memory cells among the plurality of memory cells is sequentially performed in a direction from a first memory cell on a side of the source line to a first memory cell on a side of the bit line. An operation of reading data from each of the plurality of adjacent first memory cells is performed to allow a current to flow through the string in a first direction from the source line to the bit line.
