    • Embodiments of apparatuses and methods for protecting data storage structures from intermittent errors are disclosed. In one embodiment, an apparatus includes a plurality of data storage locations, execution logic, error detection logic, and control logic. The execution logic is to execute an instruction to generate a data value to store in one of the data storage locations. The error detection logic is to detect an error in the data value stored in the data storage location. The control logic is to respond to the detection of the error by causing the execution logic to re-execute the instruction to regenerate the data value to store in the data storage location, causing the error detection logic to check the data value read from the data storage location, and deactivating the data storage location if another error is detected.
    • 公开了用于保护数据存储结构免于间歇性错误的装置和方法的实施例。 在一个实施例中,装置包括多个数据存储位置,执行逻辑,错误检测逻辑和控制逻辑。 执行逻辑是执行指令以生成数据值以存储在数据存储位置之一中。 错误检测逻辑是检测数据存储位置中存储的数据值中的错误。 控制逻辑是通过使执行逻辑重新执行用于重新生成数据值以存储在数据存储位置的指令来响应错误的检测,使得错误检测逻辑检查从数据读取的数据值 存储位置,如果检测到另一个错误,则停用数据存储位置。
