Abstract

Phase Change Memory (PCM) has recently become a promising memory system due to its appealing properties. However, PCM shows several issues to overcome that can obscure its effectiveness compared to other memory technologies. One of them is the read disturbance error (RDE), which is occurred when a cell is repeatedly read It is the main cause of reliability issues of the PCM. This paper proposes an on-demand scrubbing solution without read counters. Probability of uncorrectable error in the next RDE are modeled by the number of errors detected by error correction code. This method can reduce lGB of hardware overhead of read counters.
