Apparatus and method for copying data from one electronic demand register to another

Abstract From the Canadian patent

A non-volatile memory copy programmer, provides temporary storage into which data can be read out from a non-volatile memory of an electronic demand register of an electric meter and from which the stored data can be written into a non-volatile memory in a replacement demand register. The non-volatile memory copy programmer also produces control signals for controlling reading and writing in the non-volatile memory. A power monitor circuit in the demand register enables the storage of data from a volatile memory to the non-volatile memory in the event of a loss of power and enables restoring the data from the non-volatile to the volatile memory when the power is restored. The power monitor …
