Abstract
An apparatus and method for scrubbing spin transfer torque (STT) memory. For example, one embodiment of a apparatus comprises: a memory subsystem including at least one spin transfer torque (STT) memory, the STT memory arranged into one or more entries; and a scrub engine to ensure that the entries of the STT contain valid data, the scrub engine including analysis and processing logic to determine, for each entry, whether a specified scrubbing interval has expired and, if so, then to invalidate the entry or re-fetch data for the entry from a source and, if the scrubbing interval has not expired, then to perform error detection and/or correction on the entry.
