Abstract
Memory systems that include NAND flash memory and dynamic random access memory (DRAM) are configured to allow a considerably higher ratio of NAND to DRAM without a significant increase in write amplitude. The NAND includes a logical-to-physical (L2P) table. The DRAM includes a buffer divided into regions, an update table of recently written data and linked lists, one for each region of the buffer linking all items in the update table in that region, the DRAM maintaining a set of linked lists, each identifying all regions with the same number of updates in the update table.
