首次采用铜原子开关作为配置开关，实现了40 nm节点、2倍逻辑密度、3.8倍运算速度和3倍功耗效率的非易失性可编程逻辑（NPL）。原子开关的开关特性在缩小到64/32 nm器件面积时保持不变，并且改进的PSE在保持低漏电流的同时降低了置位电压，使得核心晶体管能够选择原子开关。开发的40 nm NPL是下一波节能计算的有力候选者。
For the first time, a 40nm-node, 2x logic density, 3.8x operation speed, and 3x power efficient, nonvolatile programmable logic (NPL) is demonstrated by using Cu atom switch for configuration switches. The switching characteristics of the atom switch are kept in scaling down to 64/32nm device area, and an improved PSE reduces set voltage while keeping low leakage current, enabling core transistors to select the atom switches. The developed 40nm NPL is a strong candidate for the next wave of energy-efficient computing.
