ABSTRACT:
A non-volatile semiconductor memory that is erased in blocks is described. The non-volatile semiconductor memory includes an active block for storing first data and a reserve block for storing second data. The second data is a copy of the first data. The copy is made during a clean-up operation prior to erasure of the active block. The non-volatile semiconductor memory also includes a mapping table for mapping a logical address of an allocation unit to a physical address of a sector within the non-volatile semiconductor memory.
