Patent ID: 8587079

Claim:
A memory device comprising: a first plurality of magnetic random access memory (MRAM) cells positioned along a first direction; a first bit line electrically connected to the first plurality of MRAM cells, the first bit line oriented in the first direction; a first plurality of field lines oriented in a second direction different from the first direction, the first plurality of field lines being spaced such that only a corresponding first one of the first plurality of MRAM cells is configurable by each of the first plurality of field lines; and a second plurality of field lines oriented in a third direction different from the first direction and the second direction, the second plurality of field lines being spaced such that only a corresponding second one of the first plurality of MRAM cells is configurable by each of the second plurality of field lines; wherein in a first mode, a magnetization direction associated with each of the first plurality of MRAM cells is settable by either of a first current flowing through one of the first plurality of field lines or a second current flowing through one of the second plurality of field lines; and wherein in a second mode, the magnetization direction associated with each of the first plurality of MRAM cells is settable by both the first current and the second current applied concurrently.
