Abstract
A method of reading data from a plurality of bits in a spin-torque magnetoresistive memory array includes performing one or more referenced read operations of the bits, and performing a self-referenced read operation, for example, a destructive self-referenced read operation, of any of the bits not successfully read by the referenced read operation. The referenced read operations can be initiated at the same time or prior to that of the destructive self-referenced read operation.
