METHOD AND SYSTEM FOR MITIGATING WRITE AMPLIFICATION IN A PHASE CHANGE MEMORY-BASED STORAGE DEVICE

摘要

One embodiment facilitates mitigating write amplification in a phase change memory-based storage device. During operation, the system receives, by a controller of the storage device, data to be stored in a phase change memory (PCM) of the storage device. The system writes, by the controller, the data to a sector of a volatile memory of the same storage device to obtain an updated portion of the sector. In response to detecting a predetermined condition, the system writes the updated portion to the PCM.
