2012 IEEE International SOC Conference, 2012•ieeexplore.ieee.orgThis paper presents a low power embedded SRAM memory design for MPEG-4 video
processors. Considering both of the process variation and aging effect, the proposed design
adopts an optimal high voltage for spatial voltage scaling to achieve high power efficiency.
Simulations in FreePDK 45nm CMOS technology show that our proposed technique can
achieve 85%, 90%, and 79% reduction in write power, read power, and leakage current,
respectively, with graceful degradation (~ 5.6%) in video quality, as compared to …
