Abstract
Data may be purged from a memory device in a manner confined to a particular partition of a memory device having two or more partitions. Logical memory blocks may be de-mapped from physical memory blocks of a first storage partition of the memory device. De-mapped physical memory blocks of the first storage partition may be listed in a local de-mapped block list uniquely associated with the first storage partition. A local purge command may be received from a host device. In response to the local purge command, at least a portion of the de-mapped physical memory blocks listed only in the local de-mapped block list are purged.
