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.

Abstract: An apparatus is described that includes a semiconductor chip memory array having resistive storage cells. The apparatus also includes a comparator to compare a first word to be written into the array against a second word stored in the array at the location targeted by a write operation that will write the first word into the array. The apparatus also includes circuitry to iteratively write to one or more bit locations where a difference exists between the first word and the second word with increasing write current intensity with each successive iteration.

Abstract: Apparatus, systems, and methods for write operations in spin transfer torque (STT) memory are described. In one embodiment, a memory comprises at least one spin-transfer torque (STT) memory device, temperature sensor proximate the STT memory device and a controller comprising logic, at least partially including hardware logic, to monitor an output of the temperature sensor, implement a first write operation protocol when the output of the temperature sensor fails to exceed a threshold temperature, and implement a second write operation protocol when the output of the temperature sensor exceeds the threshold temperature. Other embodiments are also disclosed and claimed.
