Merged-Reference-Compatible Offset-Canceling Discharge-Based Sensing Circuit for STT-MRAM in 28-nm CMOS

Merged-Reference-Compatible Offset-Canceling Discharge-Based Sensing Circuit for STT-MRAM in 28-nm CMOS 150 150

Abstract:

This article proposes an offset-canceling (OC) discharge-based sensing circuit (OCDC) for spin-transfer-torque magnetic random access memory (STT-MRAM). The proposed circuit simultaneously implements a merged reference line (MRL) architecture and threshold voltage ( $\mathbf {V}_{\mathbf {TH}}$ ) mismatch cancellation, resolving the structural incompatibility between the conventional OC schemes and MRL. A diode-connection-based, …
