Patent ID: 8885395

Claim:
A magnetoresistive logic cell (MRLC) comprising: a first magnetic tunnel junction (MTJ- 1 ) formed by a first reference layer, a first junction layer and a free layer a magnetization direction of the first reference layer being switchable by application of a first voltage pulse to the MRLC to be parallel to the free layer magnetization direction, which is unchanged by said first pulse; a second magnetic tunnel junction (MTJ- 2 ) formed by the free layer, a second junction layer and a second reference layer, MTJ- 2 having a substantially lower resistance than MTJ- 1 , the magnetization direction of the free layer being switchable to be parallel or antiparallel to the magnetization direction of the second reference layer by application of either a second or a third voltage pulse to the MRLC that leaves the magnetization direction of the first reference layer unchanged; and MTJ- 1 and MTJ- 2 being in series.
