Abstract
In a memory system having non-volatile memory and volatile memory, write data are stored in a write-coalescing buffer in the volatile memory until the write data is written to non-volatile memory. First and second level address mapping tables are stored in the volatile memory and corresponding first and second level address mapping tables are stored in the non-volatile memory, and furthermore the second level address mapping table in the volatile memory contains entries corresponding to only a subset of the entries in the second level address mapping table in the non-volatile memory. The first address-mapping table in volatile memory includes entries storing pointers to entries in the second address-mapping table in volatile memory, entries storing pointers to locations in the write-coalescing buffer, and entries storing pointers to locations in the non-volatile memory that store data.
