Abstract

MÉTODO E SISTEMA PARA MINIMIZAR IMPACTO DE OPERAÇÕES DE RENOVAÇAO NO DESEMPENHO DE MEMàRIA VOLÁTIL. Um sistema de memória é provido. O sistema inclui uma memoria volátil, um contador de renovação configurado para monitorar um número de renovações avançadas realizadas na memória volátil, e um controlador configurado para verificar o contador de renovação para determinar se uma renovação programada regularmente pode ser pulada em resposta à detecção de uma solicitação para a renovação programada regularmente.
