Method and apparatus for a volume management system in a non-volatile memory device

摘要

Embodiments for partitioning a non-volatile memory device is described. In one embodiment a memory system includes a first addressable range of memory blocks for storing different types of data. The memory system is partitioned to include a second addressable range of memory blocks capable of storing data indicating attributes of the first addressable range of memory blocks. The second addressable range of memory blocks may also be periodically updated such that the capacities of the first addressable range of memory blocks may be dynamically adjusted depending on application needs and changes to the non-volatile memory device over time. In some embodiments, one partition of a memory device may be configured for high reliability data storage while a second partition is configured for normal reliability storage.
