Abstract:
1. A magnetic memory comprising: a magnetoresistive effect element including a first magnetic layer invariable in magnetization direction, a second magnetic layer variable in magnetization direction, and an intermediate layer provided between the first magnetic layer and the second magnetic layer; an error detecting and correcting circuit which detects whether first data written in the magnetoresistive effect element includes any error and which outputs error-corrected second data when the first data includes an error; a writing circuit which generates one of a first write current and a second write current and which passes the current through the magnetoresistive effect element, the first write current including a first pulse width, the second write current including a second pulse width greater than the first pulse width; and a control circuit which controls the writing circuit to pass the second write current through the magnetoresistive effect element when the error-corrected second data is written into the magnetoresistive effect element.
