Offset-Canceling Current-Sampling Sense Amplifier for Resistive Nonvolatile Memory in 65 nm CMOS.

Resistive nonvolatile memory (NVM) is considered to be a leading candidate for next-generation memory. However, maintaining a target sensing margin is a challenge with technology scaling because of the increased process variation and decreased read cell current. This paper proposes an offset-canceling current-sampling sense amplifier (OCCS-SA) that is intended for use in deep submicrometer resisti...
