Abstract
A semiconductor storage device includes a plurality of first wirings extending in a first direction and a plurality of second wirings extending in a second direction intersecting the first direction. A plurality of memory cells are connected between the plurality of first wirings and the plurality of second wirings and include selectors each connected in series to variable resistance elements. Each selector includes a selector material switching a current flowing to the variable resistance element according to a voltage difference between the first wiring and the second wiring, and first and second electrodes sandwiching the selector material in a portion between the first wiring and the variable resistance element. A contact area between the first electrode and the selector material is less than an area of the selector material when viewed in a stacking direction of the selector and the variable resistance element.
