ABSTRACT:
A system for phased garbage collection is described, including a memory configured to store a storage system firmware, a non-volatile memory cell array configured to maintain a metablock, the metablock comprising a logical group and a buffer portion, and a processor in communication with the memory and the non-volatile memory cell array, the processor being configured to execute the storage system firmware stored in the memory, the storage system firmware comprising program instructions for receiving a write command to write a memory write to the metablock, performing a first portion of a garbage collection operation, and storing the memory write in the buffer portion of the metablock.
