Abstract
In a system that includes a host and a memory controller that is separate from the host and stores data for the host in a non-volatile memory, a method for data storage includes transferring from the memory controller to the host one or more source blocks from the non-volatile memory for compaction. The source blocks are compacted in the host by copying valid data from the source blocks into one or more destination blocks. The destination blocks are transferred from the host to the memory controller, and the destination blocks are stored by the memory controller in the non-volatile memory.
