Abstract
A method of controlling data access to non-volatile memory is disclosed. The method includes storing a data file in a non-volatile memory. The non-volatile memory includes a memory array including a plurality of address ranges one or more of which corresponding to a protected portion of the memory array and one or more of which corresponding to an unprotected portion of the memory array.
