Abstract
An arrangement for generating and storing metering information in a meter for measuring a consumed commodity includes a processing circuit and a non-volatile, rewriteable random access memory. The processing circuit is operable to generate metering information. The non-volatile, rewriteable random access memory stores metering information during normal operation, and is operable to retain the stored metering information in the absence of external electrical power.
