Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159844
Kind Code:
A1
Abstract:
In a crossbar circuit which uses a variable resistance element, this semiconductor device is provided with: a plurality of first wires which extend in a first direction so as to suppress a decrease in a voltage applied to the variable resistance element during writing and erasing; a plurality of second wires extending in a second direction; a unit element which comprises two variable resistance elements connected in series, and has one end connected to a first wire and the other end connected to a second wire; a first control line for controlling the supply of a voltage to the first wire; a second control line for controlling the supply of a voltage to the second wire; and a cell circuit connected to an intermediate node between the two variable resistance elements and also connected to the first control line and the second control line. The cell circuit has: a cell transistor connected to an intermediate node writing driver which supplies a voltage to the intermediate node; and a cell control circuit which controls an electrical conduction state of the cell transistor.
