Abstract: Ein Datenverarbeitungssystem, welches Speicher-Energiereduzierung in einem Schlafzustand verwendet. Das System kann einen flüchtigen Speicher und mindestens ein Dateneingabeperipheriegerät und eine logische Schaltung umfassen, welche eingerichtet ist zum Verwalten des Energieverbrauchs des Datenverarbeitungssystems für ein Schlafen des Systems. Die logische Schaltung kann mit dem flüchtigen Speicher gekoppelt sein und kann eingerichtet sein zum Abschalten der Energie für den flüchtigen Speicher in Antwort auf ein Ereignis, welches während dem Schlafzustand auftritt, aber ansonsten in dem Schlafzustand zu verbleiben. Der Schlafzustand kann ein ACPI-konformer S3-Schlafzustand sein, in welchem der flüchtige Speicher, wie beispielsweise DRAM, nach einer Periode von Nutzerinaktivität während des S3-Schlafzustands ausgeschaltet wird.

Abstract: A data processing system comprises a volatile memory, such as DRAM; at least one data input peripheral; and a logic circuit that is configured to manage power consumption of the data processing system during a sleep state of the system. The logic circuit is coupled to the volatile memory, and is configured to turn off power to the volatile memory in response to an event occurring during the sleep state, but to have the rest of the system remain in the sleep state. This reduces power consumption. The sleep state may be an ACPI-compliant S3 sleep state, in which the volatile memory is powered off after a period of user inactivity during the S3 state. This period may be determined by the expiration of a timer, in response to an action of the user, such as a specific key sequence or the closing of a lid, or based on a condition of the system at the time of entering the sleep state. The system may transfer the data in the volatile memory to a non-volatile memory before entering the sleep state.

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.
