ABSTRACT:
The present invention provides a reconfigurable programmable logic device (PLD) that saves its own programmed state without the use of an external memory device or without additional control logic on the PLD. A non-volatile memory cell is incorporated with each SRAM cell in the PLD to form a configuration memory cell. The non-volatile memory cells store the programmed states of the associated SRAM cells even after termination of power to the system. Each non-volatile memory cell then restores the configured state of its associated SRAM cell upon system power-up by "mapping" its contents to the SRAM cell. The non-volatile memory cell may be implemented either by an Erasable Programmable Read Only Memory cell ("EPROM") or an Electrically Erasable Programmable Read Only Memory cell ("EEPROM").
