“…The authors also proposed a detector deploying a trellis structure whose output labels are independent of the ITI. Moreover, joint detection schemes were suggested in [7, 8]. Han et al [9] proposed a channel detection scheme where the detector can estimate the TMR and then equalise the received signal using the multi‐layer perceptrons technique.…”

A design of 7/9-rate sparse code for spin-torque transfer magnetic random access memory (STT-MRAM) is proposed in this work. The STT-MRAM using spin-polarized current through magnetic tunnel junction (MTJ) to write data is regarded as the most promising candidate for the next-generation nonvolatile memory technologies in both consumer and data center applications. The proposed code is designed based on exploiting the asymmetric write failure feature of the STT-MRAM. In particular, 7-bit user-data sequences incoming the encoder is encoded into 9-bit codewords, where the Hamming weights of the codewords are equal to 2 and 4 only. A single look-up table accomplishes encoding, whereas the maximum likelihood decoding is deployed in this work. Simulation results demonstrate that the designed code can provide significant improvements for the reliability of STT-MRAM under the effect of both write and read errors.
