按集成度高低分类
集成电路按集成度高低的不同可分为:
SSIC 小规模集成电路(Small Scale Integrated circuits)
MSIC 中规模集成电路(Medium Scale Integrated circuits)
LSIC 大规模集成电路(Large Scale Integrated circuits)
VLSIC 超大规模集成电路(Very Large Scale Integrated circuits)
ULSIC特大规模集成电路(Ultra Large Scale Integrated circuits)
GSIC 巨大规模集成电路也被称作极大规模集成电路或超特大规模集成电路(Giga Scale Integration
