据TheElec，三星电子最早将在今年3月停止在华城园区12号生产线制造2D NAND闪存，该企业的2D NAND闪存时代也将随之正式结束。三星电子早在2013年就实现了3D NAND (V-NAND) 的量产，不过三星还是保留了小规模的2D NAND产能以应对特殊利基市场的需求。华城12号生产线未来将服务于1c nm DRAM内存制造，负责后端的金属布线和表面处理工艺。（财联社）
If the number of candidates for each pixel grows too large (as is common in algorithms such as Knoll and Yliluoma) then sorting the candidate list for every pixel can have a significant impact on performance. A solution is to instead sort the palette in advance and keep a separate tally of weights for every palette colour. The weights can then be accumulated by iterating linearly through the tally of sorted colours.
