Patent ID: 7668005

Claim:
A magnetic memory, comprising: a plurality of magnetoresistive elements which include a fixed layer in which a magnetization direction is fixed, a free layer in which a magnetization direction changes, and a nonmagnetic layer formed between the fixed layer and the free layer, and records data by a resistance value which changes on the basis of the magnetization direction of the free layer; a word line electrically connected to first terminals of the magnetoresistive elements; a plurality of bit lines electrically connected to second terminals of the magnetoresistive elements, respectively; and a current controller configured to, during data erase, supply a current to the word line to generate a magnetic field without supplying a current to the bit lines, set the magnetization direction of the free layer in a first direction by the magnetic field, and erase data of the magnetoresistive elements electrically connected to the word line by one time data erase, and during data write, supply a current in one direction to each magnetoresistive element using the word line and the bit lines, and set the magnetization direction of the free layer in a second direction by spin transfer magnetization reversal.
