Definition of "VLSI" |
very large scale integration. (10,000 to 99,999 gates per chip) / Very Large-Scale Integration, / Very large scale integration refers to an IC or technology with many devices on one chip. The question, of course, is how one defines "many."The term originated in the 1970s along with "SSI" (small scale integration), "LSI" (large scale), and several others, defined by the number of transistors or gates per IC. It was all a bit silly since improving technology obviously makes numerical definitions meaningless over time. And it varies by industry a VLSI analog part is quite different from a VLSI digital logic part or a VLSI memory part.Eventually, the pundits began trying terms like "ULSI" (ultra large scale). / Very-large-scale integration is the process of creating integrated circuits by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. / Wideband is a transmission medium or channel that has a wider bandwidth than one voice channel with a carrier wave of a certain modulated frequency. / See very-large-scale-integration. |
