The invention includes a magnetoresistive memory device having a memory bit stack. The stack includes a first magnetic layer, a second magnetic layer, and a non-magnetic layer between the first and second magnetic layers. A first conductive line is proximate the stack and configured for utilization in reading information from the memory bit. The first conductive line is ohmically connecting with either the first or second magnetic layer. A second conductive line is spaced from the stack by a sufficient distance that the second conductive line is not ohmically connected to the stack, and is configured for utilization in writing information to the memory bit. The invention also includes methods of storing and retrieving information.
