STAxCache: An approximate, energy efficient STT-MRAM cache

Abstract

STT-MRAM has attracted great interest for use as on-chip memory due to its high density, near-zero leakage and high endurance. However, its overall energy efficiency is limited by the energy requirements of spin-transfer torque switching during writes and reliable single-ended sensing during reads. Leveraging the ability of many applications to produce… (More)
