Patent ID: 7957181

Claim:
A magnetic memory with a thermally-assisted write, every storage cell of which consists of at least one magnetic tunnel junction, said tunnel junction comprising at least: one magnetic reference layer, the magnetization of which is always oriented in the same direction at the time of the read of the storage cell; one so-called “free” magnetic storage layer, the magnetization direction of which is variable; one insulating layer sandwiched between the reference layer and the storage layer, wherein the magnetization direction of the reference layer is polarized in a direction that is substantially always the same at the time of a read due to magnetostatic interaction with another fixed-magnetization layer called the “polarizing layer” and in that the polarizing layer is arranged so that it is subjected, during read phases and write phases, to thermal variations that are less than those to which the reference layer with which it interacts magnetostatically is subjected.
