The sneak path (SP) interference problem in resistive random access memory (ReRAM) severely affects the data storage reliability. Recent works showed that the occurrence of the SP is highly related to the selector failures (SFs) in the resistive memory arrays. In this work, we propose a novel scheme to detect the location of the failed selector, based on the signal read back from the memory array. The detected SF location information can be used to assist the data detection to mitigate the SP interference or to construct SP-free constrained codes.
