该论文提出了一种基于铁电电容的非易失性D触发器(NVDFF),能够在频繁断电时保持电路状态,适用于能量采集和常关系统。通过嵌入式铁电电容实现数据鲁棒感知,避免了竞争问题,并实现了3.4pJ的低能耗。
Texas Instruments, Dallas, TX 1 2 Nonvolatile processing—continuously operating a digital circuit and retaining state through frequent power interruptions—creates new applications for portable electronics operating from harvested energy [1] and high-performance systems managing power by operating “normally off” [2]. To enable these scenarios, energy processing must happen in parallel with information processing. This work makes the following contributions: 1) the design of a nonvolatile D flip-flop (NVDFF) with embedded ferroelectric capacitors (fecaps) that senses data robustly and avoids race conditions; 2) the integration of the NVDFF into the ASIC design flow with a power management unit (PMU) and a simple one-bit interface to brown-out detection circuitry; and 3) a characterization of the NVDFF statistical signal margin and the energy cost of retaining data. This chip’s process technology features embedded ferroelectric capacitors that
