摘要

New phase-change memory (PCM) devices have low-access latencies (like DRAM) and high capacities (i.e., low cost per bit, like Flash). In addition to being able to scale to smaller cell sizes than DRAM, a PCM cell can also store multiple bits per cell (referred to as multilevel cell, or MLC), enabling even greater capacity per bit. However, reading and writing the different bits of data from and to an MLC PCM cell requires different amounts of time: one bit is read or written first, followed by another. Due to this asymmetric access process, the bits in an MLC PCM cell have different access latency and energy depending on which bit in the cell is being read or written.
