Magnetic storage device with voltage generator that varies voltages according to temperature
First Claim
1. A magnetic storage device comprising:
- a memory cell including a magnetoresistive effect element, the magnetoresistive effect element including a storage layer and a reference layer;
a first line electrically coupled to a first terminal of the magnetoresistive effect element;
a second line electrically coupled to a second terminal of the magnetoresistive effect element;
a temperature detection element configured to detect a temperature;
a write driver; and
a voltage generator,wherein the voltage generator generates a first voltage, and varies the generated first voltage according to the temperature,wherein the write driver supplies the varied first voltage to the first line in a first write operation in which a first resistance value of the magnetoresistive effect element is changed to a second resistance value smaller than the first resistance value, andwherein the voltage generator is configured such that the generated first voltage has a negative correlation with the temperature.

Abstract
According to an embodiment, a magnetic storage device includes a memory cell including a magnetoresistive effect element including a storage layer and a reference layer; first and second line electrically coupled to the magnetoresistive effect element; and a write driver. The write driver supplies a first voltage to the first line in a first write operation in which a first resistance value of the magnetoresistive effect element is changed to a second resistance value smaller than the first resistance value, and supplies a second voltage different from the first voltage to the second line in a second write operation in which the second resistance value of the magnetoresistive effect element is changed to the first resistance value.
