High Speed and Low Power Sensing Schemes for STT-MRAM with IPMTJs

Abstract

STT-MRAM with interfacial-anisotropy-type perpendicular MTJ (IPMTJ) is a powerful candidate for the low switching energy design of STT-MRAM. In the literature, the reading operation of STT-MRAM structured with IPMTJs have been not studied until this time, in our knowledge. We investigated the reading operation of STT-MRAM structured with IPMTJs. To enumerate the read operations of the NVSenseAmp have successfully been performed a 2.5X reduction in average low power and a 13X increase in average high speed compared with the previous works.
