Abstract
A perpendicular STT-MRAM comprises apparatus, a method of operating and a method of manufacturing a spin-torque magnetoresistive memory and a plurality of magnetoresistive memory element having a recording layer which has an interface interaction with an underneath dielectric functional layer. The energy switch barrier of the recording layer is reduced under an electric field applying along a perpendicular direction of the functional with a proper voltage on a digital line from a control circuitry; accordingly, the perpendicular magnetization of the recording layer is readily reversible in a low spin-transfer switching current.
