Abstract
A method and system for controlling data in a computer system when the computer system loses power is disclosed. The method and system comprises activating a plurality of super capacitors to supply power to the computing engine based upon power being removed from the computer system and reconfiguring the data in the computing engine. Through the use of a system and method, large amounts of newly written and modified data can be stored from the volatile memory to the non-volatile memory in the event of a sudden external system power loss. The system and method allows data to be rapidly and irretrievably erased from the non-volatile memory automatically, in the event of a sudden loss of external power, or manually. This capability consumes minimal space and weight and is implemented in an affordable manner.
