Method of using flash memory for storing metering data

摘要

The invention relates to a method of storing continuously updated meter data in a utility meter, comprising the steps of: providing a plurality of memory structures including at least one associated memory buffer characterized by a first predetermined storage size and a non-volatile flash memory structure having a plurality of flash memory blocks each characterized by a second predetermined storage size; obtaining updated meter data representative of a measured or distributed amount of utility product or service; storing said updated meter data in the at least one associated memory buffer; detecting when power to the utility meter is disabled; and copying the updated meter data in said at least one associated memory buffer into at least one selected flash memory block of said non-volatile flash memory structure, wherein said at least one selected flash memory block is determined via a flash pointer indicative of such location.
