Abstract:
A magnetoresistive memory device, comprising:a memory bit comprising a stack which includes a first magnetic layer, a second magnetic layer, and a non-magnetic layer between the first and second magnetic layers; the memory bit storing information as a relative orientation of a magnetic moment in the first magnetic layer to a magnetic moment in the second magnetic layer; a first conductive line proximate the stack and configured for utilization in reading information from the memory bit; a second conductive line spaced from the stack by a greater distance than any distance which the first conductive line is spaced from the stack, and configured for utilization in writing information to the memory bit; wherein the first and second conductive lines extend longitudinally parallel to one another; wherein the first conductive line is not utilized in writing information to the memory bit; and wherein the second conductive line is not utilized in reading information from the memory bit.
