US 2020/0395084 A1 · SEMICONDUCTOR STORAGE DEVICE

Abstract

A semiconductor storage device includes a first memory cell and a second memory cell which are connected to each other in series, a first word line which is connected to the first memory cell, a second word line which is connected to the second memory cell, and a control circuit. The control circuit is configured to charge a first node while applying a second voltage to the second word line and a first voltage to the first word line, to charge a second node on the basis of a voltage of the charged first node, to discharge the second node while applying the second voltage to the second word line and a third voltage to the first word line, and to read data from the first memory cell on the basis of voltages of the charged and discharged second node.
