    摘要: In one embodiment, the present invention includes a method for determining a vulnerability level for an instruction executed in a processor, and re-executing the instruction if the vulnerability level is above a threshold. The vulnerability level may correspond to a soft error likelihood for the instruction while the instruction is in the processor. Other embodiments are described and claimed.

    摘要: 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.

    摘要: An NBTI-resilient memory cell is made up of a ring of multiple NAND gates. The NAND gates are arranged such that one of the NAND gates has a “0” in its output, while the remaining NAND gates have a “1” in their outputs. PMOS transistors within the memory cell experience less degradation than in inverter-based memory cells. Guard-banding to account for transistor degradation may be mitigated, or the operating frequency of the memory cell may be increased.
