First, a brief discussion of the construction and operation of STT-MRAM, and the mechanism of operation of STT-MTJ devices is presented. Circuit sensing techniques are then introduced and divided into two categories - current mode and voltage mode - according to their sensing scheme. These techniques are described in detail with comprehensive case studies from literature, followed by a thorough comparison and discussion of their respective design space.
