摘要：
A non-volatile memory system writes logical to physical conversion data to the same memory blocks as user data, and as part of the same page as a segment of user data, as data segments are received and written. When a data block is subsequently compacted and obsolete data removed, the user data from the block is written to a one block and some or all of the logical to physical conversion data from the block is written to another block dedicated for the storage of such logical to physical mapping data.
