METHOD OF WRITING AND READING DATA IN AN NVM USING LPAGE IDENTIFICATION HEADERS

A method includes the steps of storing a logical page (Lpage) identification header in each starting read unit of a non-volatile memory (NVM), a starting read unit defined as a first read unit in an Lpage, the Lpage comprising a plurality of contiguous sectors of data present in the NVM; reading a table with an address mapping function of a storage controller in communication with the NVM; and responsive to the step of reading the table, referencing an Lpage by a read unit address. A size of the table is thereby smaller than a size of a conventional table that must store a byte address of every read unit in the NVM, the smaller size of the table resulting in greater efficiency in reading the table over reading the conventional table.
