提出了一种适用于MPEG4视频处理器的低功耗嵌入式SRAM存储器设计方案。该设计综合考虑了工艺变化和老化效应，采用最优的高压进行空间电压调节，以实现高功率效率。在FreePDK 45 nm工艺下的模拟结果表明，与传统的SRAM设计相比，该技术的写入功率、读取功率和泄漏电流分别降低了85%、90%和79%，而视频质量下降了约5.6%。
This 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 conventional SRAM design.
