Abstract
A novel read-while-write (RWW) algorithm for phase change memory (PCM) is proposed. It performs the verify operation for last cell, the write operation for current cell and the pre-read operation for next cell simultaneously. Therefore, it can reduce the timing cost by the data-comparison write (DCW) algorithm and the program & verify (P&V) algorithm. The performance analysis and simulation results show that the percent of saving timing by RWW is >22.6%.
