IMPLEMENTING ENHANCED PHASE CHANGE MEMORY (PCM) READ LATENCY THROUGH CODING

摘要

A method, apparatus, and storage device are provided for implementing enhanced performance with enhanced phase-change-memory (PCM) read latency through coding. A coding algorithm is used to write data to the PCM including a redundancy chip enabling recovery of inaccessible partition data by reading other partitions. A read operation is served by reading parity lines and computing data for the read operation from a blocked written-to partition.

1. A method for implementing enhanced performance with enhanced phase-change-memory (PCM) read latency to phase-change-memory (PCM) comprising:
providing the PCM including a redundancy chip; using a coding algorithm to write data to the PCM including the redundancy chip enabling recovering inaccessible partition data by reading other partitions; and serving a read operation from an otherwise blocked written-to partition by reading parity lines from other partitions and computing data for the read operation.
