Abstract
A ferroelectric memory array (20) monolithically integrated with a field programmable gate array (32) into a semiconductor circuit (10). The ferroelectric memory array (20) is suitable for a semiconductor manufacturer to program the configuration data that is used in the field programmable gate array (32) prior to shipment and installation in an electronic system. The memory array (20) provides the data that configures the field programmable gate array (32) for functionality of the Configurable Logic Blocks (CLBs) in the field programmable gate array (32). Should the field programmable gate array (32) circuit lose power, the non-volatile memory array (20) provides a shift register (26) with the data to reconfigure the field programmable gate array (32).
