We proposed the systematic tools, RAMSES-M and TAGS-M, for test and diagnosis algorithms evaluation and development, respectively. In addition to traditional memory fault models, the tools support the MRAM specific fault model, Write Disturbance Fault (WDF) and its specific test operation, Read-previous, which is proposed in this paper, too. The concept of Weighted Fault Coverage (WFC) is introduced...
To help improve quality and yield of magnetic random access memory (MRAM), we propose an adaptive diagnosis algorithm (ADA) that can efficiently identify the write disturbance fault (WDF) for MRAM. The proposed test algorithm is a March-based one, i.e., it has linear time complexity and can easily be implemented with built-in self-test (BIST). However, the proposed test method can evaluate the process...
