SYSTEMS AND METHODS FOR WRITE PROTECTION OF NON-VOLATILE MEMORY DEVICES

摘要

A write protection mechanism may be implemented that is external to a non-volatile memory device and/or that is external to controller/s that interface with the non-volatile memory device, thus providing increased security over unauthorized and/or undesirable write cycles to the memory device. Write protection security may be further enhanced by providing a write protection control signal that is external to the non-volatile memory and attached memory controller/s, thus preventing accidental or intentional override.
