ABSTRACT:
A method and apparatus are disclosed for reclaiming solid state storage with limited write cycles such as flash memory. Through the use of shared storage for common data patterns, physical space may be conserved or reclaimed in a solid state device. The apparatus may use internal mappings and/or external device drivers to handle the reclamation of unused space. By enabling reclamation of physical space, the disclosed systems, apparatus, and methods may provide more efficient read and write access and improved wear leveling.
