Abstract(in English) | This paper presents a novel read-bitline amplitude limiting (RBAL) scheme which suppresses dynamic energy dissipation caused by random variation. In addition, a discharge acceleration (DA) circuit is proposed to decrease delay overhead of RBAL. The proposed scheme improves the active energy dissipation in a read cycle by 22% at the center-center (CC) corner and 25℃. The maximum delay overhead is 32% at the fast-slow (FS) corner and -40℃. The circuits have been implemented using the 40-nm bulk CMOS process. The implemented 256-Kb 8T SRAM works fine with energy dissipation of sub-10 pJ / access from 0.5-0.7V. |
