1. An arrangement for generating and storing metering information in a meter for measuring a consumed commodity, the arrangement including:
- a) a processing circuit operable to receive commodity consumption information and generate metering information therefrom;
b) a non-volatile, rewriteable random access memory for storing the metering information during normal operation, the non-volatile, rewriteable random access, memory operable to retain the stored metering information in the absence of electrical power from a source external to the non-volatile, rewriteably random access memory.

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.
