METHOD AND SYSTEM FOR STORAGE ADDRESS RE-MAPPING FOR A MULTI-BANK MEMORY DEVICE

摘要

A method and system for storage address re-mapping in a multi-bank memory is disclosed. The method includes allocating logical addresses in blocks of clusters and re¬ mapping logical addresses into storage address space, where short runs of host data dispersed in logical address space are mapped in a contiguous manner into megablocks in storage address space. Independently in each bank, valid data is flushed within each respective bank from blocks having both valid and obsolete data to make new blocks available for receiving data in each bank of the multi-bank memory when an available number of new blocks falls below a desired threshold within a particular bank.
