摘要

在ITRS的长期预测中,FinFET器件是进一步技术扩展最有前途的解决方案。通过通道长度从20nm到7nm的技术缩放,对基于finfet的超尺度256位SRAM的性能进行了评估,显示了基本性能指标的缩放趋势。此外,考虑到模对模的变化,阈值电压变化对延迟、功率和稳定性的影响被报道。从10nm通道长度开始到7nm通道长度,性能显著下降。

Performance evaluation of finFET based SRAM under statistical VT variability
FinFET devices are the most promising solutions for further technology scaling in the long term projections of the ITRS. The performance of extremely scaled FinFET-based 256-bit (6T) SRAM is evaluated with technology scaling for channel lengths of 20nm down to 7nm showing the scaling trends of basic performance metrics. In addition, the impact of threshold voltage variations on the delay, power, and stability is reported considering die-to-die variations. Significant performance degradation is found starting from the 10nm channel length and continues down to 7nm.
