Integrated circuit device having state-saving and initialization feature

An integrated circuit device having an initialization feature comprising:

• a programmable logic block;
• at least one volatile data storage unit;
• a non-volatile memory block;
• a device-startup controller circuit;
• a boundary-scan register chain selectively coupleable to said at least one volatile data storage unit;
• and
• a control circuit coupled to and responsive to said device-startup controller circuit, said control circuit operable to selectively couple said boundary-scan register chain to said at least one volatile data storage unit and to write data from said non-volatile memory block into said at least one volatile data storage unit.

An integrated circuit device having a state-saving feature comprising:

• a programmable logic block;
• a plurality of I/O structures;
• at least one dedicated register;
• at least one volatile memory block;
• a non-volatile memory block;
• a condition-sensing circuit for detecting at least one condition;
• interface logic coupled to at least one of said plurality of I/O structures, outputs of said at least one dedicated register, outputs of said at least one volatile memory block, and inputs of said non-volatile memory block;
• and
• a control circuit coupled to and responsive to said condition-sensing circuit, said control circuit operable to selectively operate said interface logic to write data from at least one of said at least one of said plurality of I/O structures, outputs of said at least one dedicated register, outputs of said at least one volatile memory block into said non-volatile memory block.
