Abstract:
A method for storing meter data comprising the steps of:providing a plurality of memory structures, wherein said plurality of memory structures includes at least one multi-segmented non-volatile memory structure and at least one additional associated memory structure; measuring a plurality of utility-provider defined metering data; detecting the existence of newly acquired or updated metering data; determining a segment of said at least one non-volatile memory structure where the newly acquired or updated metering data is to be stored; reading the data from the non-volatile memory structure segment from said determining step into said associated memory structure; altering selected data within the associated memory structure; erasing the segment of the non-volatile memory structure that was transferred in said step of reading the data; and rewriting the altered data from the associated memory structure to the erased segment of said non-volatile memory structure.
