Abstract
Apparatus and method contemplating a magnetoresistive memory apparatus having a read element having a high resistance material selected to optimize read sensitivity and a write element having a material selected for a lower critical current response than the read element critical current response to optimize switching efficiency, wherein the read element resistance is higher than the write element resistance, and a shared storage space for both elements.
Claims5
A magnetoresistive memory apparatus comprising:
- a read element having a high resistance material selected to optimize read sensitivity;
- a write element having a material selected for a lower critical current response than the read element critical current response to optimize switching efficiency, wherein the read element resistance is higher than the write element resistance;
- and
- a shared storage space for both elements.

A method comprising:
- obtaining a magnetoresistive memory apparatus having a read element constructed of a high resistance material selected to optimize read sensitivity, and a write element constructed of a material selected for a lower critical current response than the read element critical current response to optimize switching efficiency, wherein the read element resistance is higher than the write element resistance, and a shared storage space for both elements;
- energizing the write element with a write current having a first amperage to write data to the shared storage space;
- and
- energizing the read element with a read current having a second amperage lower than the first amperage to read data from the shared storage space.
