Abstract

A semiconductor storage device includes a plurality of word line layers stacked above one another in a first direction, a memory pillar having a columnar body penetrating the plurality of the word line layers, wherein each portion of the memory pillar intersecting the word line layers functions as a memory cell transistor, a source line layer to which an end of the memory pillar is connected, an acquisition circuit configured to acquire a voltage of the source line layer, and a first adjustment circuit configured to adjust the voltage of the source line layer to a predetermined target voltage based on the acquired voltage. The acquisition circuit includes a dummy pillar having a columnar body penetrating the plurality of word line layers and having an end connected to the source line layer, wherein each portion of the dummy pillar intersecting the word line layers functions as a dummy transistor.
