摘要: In general, in one aspect, the disclosure describes an apparatus that includes a memory device having a plurality of memory cells. An inverter is used to invert data and tag information destined for the memory device. A register is used to capture the inverted data and tag information. A write inverted value logic is used to determine when to enable writing the inverted data and tag information from the register to the memory device. When inverted data and tag information is written to a memory cell the memory cell is invalidated.

摘要: Methods and apparatus to reduce aging effect on registers are described. In one embodiment, a select value is stored in a register that is unused, for example, to reduce the effects of negative bias temperature instability (NBTI) or oxide degradation on the register. Other embodiments are also described.

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.
摘要翻译: NBTI弹性存储单元由多个NAND门的环组成。 NAND门被布置成使得一个NAND门在其输出中具有“0”,而其余的NAND门在其输出中具有“1”。 存储器单元内的PMOS晶体管比基于逆变器的存储单元中的PMOS晶体管的衰减更少。 可以减轻保护带以解决晶体管劣化,或者可以增加存储单元的工作频率。
