Memory mapping techniques for non-volatile memory are disclosed where logical sectors are mapped into physical pages using data structures in volatile and non-volatile memory. In some implementations, a first lookup table in non-volatile memory maps logical sectors directly into physical pages. A second lookup table in volatile memory holds the physical address of the first lookup table in non-volatile memory. In some implementations, a cache in volatile memory holds the physical addresses of the most recently written logical sectors. Also disclosed is a block TOC describing block content which can be used for garbage collection and restore operations.
