N2 - Phase change memory (PCM) is a promising technology for building future large-scale and low-power main memory systems. Main memory databases (MMDBs) can benefit from the high density of PCM. However, its long write latency, high write energy, and limited lifetime, bring challenges to database algorithm design for PCM-based memory systems. In this paper, we focus on making B +-tree PCM-friendly by reducing the write accesses to PCM. We propose three different schemes. Experimental results show that they can efficiently improve the performance, reduce the memory energy consumption, and improve the lifetime for PCM memory.
