Data Encoding Technique to Enhance the Reliability of STT-MRAM Memory

Abstract

Spin-Transfer Torque Magnetic Random Access Memory (STT-MRAM) has emerged as a promising technology for future memory systems due to its non-volatility, high endurance, and low power consumption. However, STT MRAM has limitations in terms of read-disturbance, which can lead to data errors and affect the reliability and lifetime of the device. This thesis pro poses an architecture-level encoding scheme to mitigate read-disturbance in STT-MRAM. The proposed scheme is based on an encoding approach that modifies the data being written to the STT-MRAM to ensure that the prob ability of read-disturbance errors is reduced. The proposed encoding scheme is evaluated through simulation experiments, and the results demonstrate significant improvements in the reliability and lifetime of the STT-MRAM device.
