    Abstract: An apparatus and method for scrubbing spin transfer torque (STT) memory. For example, one embodiment of a apparatus comprises: a memory subsystem including at least one spin transfer torque (STT) memory, the STT memory arranged into one or more entries; and a scrub engine to ensure that the entries of the STT contain valid data, the scrub engine including analysis and processing logic to determine, for each entry, whether a specified scrubbing interval has expired and, if so, then to invalidate the entry or re-fetch data for the entry from a source and, if the scrubbing interval has not expired, then to perform error detection and/or correction on the entry.

    Abstract translation: 一种用于清洗自旋转移转矩(STT)存储器的装置和方法。 例如,设备的一个实施例包括:存储器子系统,其包括至少一个自旋转移转矩(STT)存储器,STT存储器被布置成一个或多个条目; 以及擦除引擎,以确保STT的条目包含有效数据,擦洗引擎包括分析和处理逻辑,以确定每个条目是否指定的擦除间隔已过期,如果是,则使该条目或重新生效 - 从源中获取条目的数据,如果擦除间隔尚未过期,则对条目执行错误检测和/或更正。
