GARBAGE COLLECTION IN HYBRID MEMORY SYSTEM

摘要

A hybrid memory system includes a primary memory and a secondary memory. A garbage collection operation is performed on the hybrid memory system. A read operation comprising reading data from a first cluster of a plurality of clusters is performed. Responsive to a determination that the read operation failed, the first cluster is unmapped without writing the data to a second cluster and the first cluster continues to be used for subsequent data storage. Responsive to a determination that the read operation did not fail, data is written to the second cluster.

1. A method of performing garbage collection in a hybrid memory system that includes a primary memory and a secondary memory, the method comprising:
performing a read operation comprising reading data from a first cluster of a plurality of clusters; responsive to a determination that the read operation failed, unmapping the first cluster without writing the data to a second cluster and continuing to use the first cluster for subsequent data storage; and responsive to a determination that the read operation did not fail, writing the data to the second cluster.
