Abstract
A magnetic storage device includes a memory cell with a magnetoresistive effect element and a switching element connected in series. The magnetoresistive effect element is configured to change from a first resistance state to a second resistance state that is lower in resistance than the first resistance state in response to a first write operation flowing current in a first direction through the memory cell and to change from the second resistance state to the first resistance state in response to a second write operation flowing current in a second direction through the memory cell. The switching element has a first voltage drop associated with current flows in the first direction and has a second voltage drop associated with current flows the second direction that is lower than the first voltage drop.
