PHASE-CHANGE MEMORY MAY ENABLE CONTINUED SCALING OF MAIN MEMORIES, BUT
PCM HAS HIGHER ACCESS LATENCIES, INCURS HIGHER POWER COSTS, AND WEARS OUT
MORE QUICKLY THAN DRAM. THIS ARTICLE DISCUSSES HOW TO MITIGATE THESE
LIMITATIONS THROUGH BUFFER SIZING, ROW CACHING, WRITE REDUCTION, AND WEAR
LEVELING, TO MAKE PCM A VIABLE DRAM ALTERNATIVE FOR SCALABLE MAIN MEMORIES
