[Problem] To perform data readout at a low voltage without reducing reliability. [Solution] A sense amplifier is provided with a memory string that includes memory cells, a bit line electrically connected to one end of the memory string, and a sense amplifier which is electrically connected to the bit line and which performs sensing. The sense amplifier comprises: a first transistor for which one end is electrically connected to a first node upon an electrical current path of the bit line, and for which the other end is electrically connected to a second node; a second transistor which is electrically connected between the second node and a sense node; and a third transistor for which a gate is connected to the first node, and which is electrically connected between the second node and a voltage-adjustable third node. |
