Abstract
In one embodiment, a programmable logic device (PLD) such as a field programmable gate array (FPGA) includes a non-volatile memory adapted to store a first bit, a second bit, and a plurality of configuration data. A plurality of configuration memory cells within the PLD is adapted to receive configuration data transferred from the non-volatile memory. The PLD further includes control logic adapted to determine based on the logic states of the first and second bits stored in the non-volatile memory and prior to any transfer of the configuration data whether to transfer the configuration data from the non-volatile memory to the configuration memory cells.
