Abstract

Un sistema de procesamiento de datos que utiliza reducción de energía de memoria en un estado inactivo. El sistema puede incluir una memoria volátil y al menos un periférico de entrada de datos y un circuito lógico que se configura para manejar consumo de energía del sistema de procesamiento de datos durante una inactividad del sistema. El circuito lógico puede acoplarse a la memoria volátil y puede configurarse para desconectar la energía en la memoria volátil en respuesta a un evento, que se presenta durante el estado inactivo, pero permanece de otra manera en el estado inactivo. El estado inactivo puede ser un estado inactivo S3 que cumple con ACPI en el cual la memoria volátil, tal como DRAM, se apaga después de un periodo de inactividad de usuario durante el estado inactivo S3.
