Abstract
Methods and devices are disclosed herein to provide improved techniques for securing configuration data stored in non-volatile memories of programmable logic devices. For example, in accordance with an embodiment of the present invention, a programmable logic device includes a non-volatile memory adapted to store a plurality of configuration data. A plurality of security fuses are adapted to store a plurality of logic states. Control logic is adapted to selectively secure the configuration data within the non-volatile memory based on the logic states stored in the plurality of security fuses.
