Method and apparatus for retaining programming in a volatile memory unit

摘要

A small portable power supply is connected to a circuit board comprising a volatile memory unit. The main circuit board power supply is then disconnected from the circuit board, and the board may now be physically moved to another location without the loss of the data contained within the volatile memory. At the new location, another main circuit board power supply may be connected to the circuit board, and the small portable power supply may be disconnected, completing the transfer of the circuit board without any loss of data.
