Abstract

"MéTODO PARA USAR MEMóRIA FLASH PARA ARMAZENAMENTO DE DADOS DE MEDIDOR". Uma estrutura de memória flash não volátil de segmento múltiplo é empregada em combinação com pelo menos uma estrutura de memória associada para o armazenamento, a atualização e a preservação de dados de medidor. Pelo armazenamento inicial de dados de medidor na memória associada, os dados de medidor são armazenados em buffer até que uma quantidade predeterminada de dados seja obtida ou até que a potência para o medidor seja desabilitada (124), em cujo ponto os dados de medidor armazenados são copiados para blocos selecionados de memória flash (126). As várias localizações para dados de transferência são respectivamente determinadas por ponteiros de flash indicando quais segmentos ou blocos de memória flash utilizar. Em algumas modalidades, o tamanho da estrutura de memória associada corresponde ao tamanho de cada segmento de memória flash, para a maximização da transferência de dados, quando a estrutura de memória associada estiver cheia e, também, para a redução do número de vezes que a memória flash é escrita, desse modo aumentando o intervalo de vida ativo potencial da memória flash.
