ABSTRACT:
Systems and methods are directed to verification of configuration data stored in memory cells. For example, in one embodiment, an integrated circuit such as a programmable logic device includes a plurality of non-volatile memory cells and a plurality of volatile memory cells adapted to receive and store data provided from the plurality of non-volatile memory cells. A comparator is adapted to compare stored data from the plurality of volatile memory cells with the data values of the plurality of non-volatile memory cells. Control circuitry is responsive to the comparator to control whether configuration data from the plurality of non-volatile memory cells is loaded to the plurality of volatile memory cells.
