    • A system and method for maintaining persistent data during an unexpected power loss uses a memory controller and a supplemental power source. An entity running on the computer, for example, an application program, a utility, the operating system or other entity, may identify data for preservation using an application program interface. The application program interface may be provided by the memory controller. A sensor determines when an unexpected power loss has occurred and signals the memory controller. Using power from the supplemental power source, i.e. a battery or capacitor, the memory controller copies the identified data to a non-volatile memory. The memory controller may set a flag to indicate that preserved data is available for later recovery.
    • 在意外的功率损耗期间维护持久数据的系统和方法使用存储器控制器和补充电源。 在计算机上运行的实体,例如应用程序,实用程序,操作系统或其他实体,可以使用应用程序接口识别用于保存的数据。 应用程序接口可以由存储器控制器提供。 传感器确定何时发生意外的功率损耗并向存储器控制器发出信号。 使用来自补充电源(即,电池或电容器)的电力,存储器控制器将识别的数据复制到非易失性存储器。 存储器控制器可以设置标志以指示保留的数据可用于稍后的恢复。

    • A method and apparatus for saving, retrieving, and adjusting metering data uses information about the period between saves of the metering data to non-volatile memory and other information, for example, a number of recovery events experienced by the computer. Adjusting the retrieved metering data according to the number of recovery events may discourage attempts by a subscriber to time power interruptions in an effort to advantageously use the metering data restoration process. Similarly, the time between saves of the metering data may be altered to help thwart such timing attacks. Information about the time between saves, or the period of the save cycle, may also be stored with the metering data for use in the metering data restoration process.
    • 用于保存,检索和调整计量数据的方法和装置使用关于计量数据保存到非易失性存储器和其他信息(例如计算机经历的许多恢复事件)之间的周期的信息。 根据恢复事件的数量调整检索的计量数据可能阻止用户尝试计时电力中断,以便有利地使用计量数据恢复过程。 类似地,可以改变计量数据的保存之间的时间以帮助阻止这种定时攻击。 关于保存之间的时间或保存周期的时间的信息也可以与计量数据一起存储以用于计量数据恢复处理。
