Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/116932
Kind Code:
A1
Abstract:
A semiconductor device of the present disclosure is provided with: a memory cell which has a first terminal, a second terminal, a storage element that can assume a first resistance state and a second resistance state, and a non-linear element; and a driving control unit which performs a first operation in which a resistance state of the storage element is put in the first resistance state by causing a first voltage of the first terminal to be higher than a second voltage of the second terminal, a second operation in which a resistance state is put in the second resistance state by causing the first voltage to be lower than the second voltage, a third operation in which a resistance state is determined by causing the first voltage and the second voltage to be different from each other and limiting, to a first current value or smaller, a current value of a current flowing between the first terminal and the second terminal, and a fourth operation in which the first voltage and the second voltage are different from each other and the current value is limited to be a second current value or smaller. The driving control unit performs the fourth operation after performing at least one among the first to third operations.
