ABSTRACT:
A system and method for selective write protection for a non-volatile memory device which comprises a superset of the existing JEDEC 21-C standard and in which user definable portions of a non-volatile memory device can be write protected instead of only the entire device. The write-protection technique of the present invention can be selectably enabled or disabled dynamically as determined by a user. Moreover, the system and method of the present invention provides for storage of the device write-protection configuration in non-volatile memory in order that the device can be restored to its last known write-protection state in the event it is powered down or the current configuration is otherwise lost.
