Integrated circuits can be divided into the following categories

According to the number of microelectronic devices integrated on a chip, integrated circuits can be divided into the following categories:
Small Scale Integration (SSI) has less than 10 logic gates or 100 transistors.
Medium Scale Integration (MSI) has 11 to 100 logic gates or 101 to 1k transistors.
Large Scale Integration (LSI) has 101-1k logic gates or 1001-10k transistors.
Very Large Scale Integration (VLSI) has 1001-10k logic gates or 10001-100k transistors.
Ultra Large Scale Integration (ULSI) has 10001-1M logic gates or 100001-10M transistors.
GLSI (Giga Scale Integration) has more than 1000001 logic gates or more than 10000001 transistors.
