SYSTEMS AND METHODS FOR MANAGING AN ARTIFICIALLY LIMITED LOGICAL SPACE OF NON-VOLATILE MEMORY

Abstract:

Systems and methods for managing non-volatile memory devices are provided. Embodiments discussed herein define a native logical space to manage relatively high volume data write operations and define an artificially limited logical space to manage relatively low volume data write operations. The native logical space may include native logical bands that are mapped to a native number of physical blocks to enable high volume, high data transfer of data. The artificially limited logical space may include artificially limited logical bands that are mapped to an artificially limited number of available physical blocks. The artificially limited logical bands are better suited for low volume, low data transfer of data and do not unnecessarily tie up a native number of physical blocks.
