Abstract

Min-delay (MID) error rates increase dramatically under aggressive voltage and technology scaling,limiting VMIN. Pulsed latches offer significant clocking power savings over flip-flops but further aggravate MID failures. This letter proposes MID margin/error detection and correction (M2/EDAC) for flip-flops and pulsed latches to reduce VMIN guard bands for voltage noise,temperature variation,and aging,and to detect and correct rare MID failures. Statistical data collection from a prototype in 10-nm tri-gate CMOS shows up to 122-mV VMIN reduction. Reliable pulsed latches enabled by M2/EDAC offer 12%-18% total dynamic power savings for logic blocks in 10-nm CMOS.
