integration density; degree of integration
Technical term used in electronics and semiconductor engineering to describe how many components (e.g., transistors) are packed onto a single chip or circuit.
This processor has a very high degree of integration.
With the improvement in integration density, chip performance has increased dramatically.
Compound of 集積 (しゅうせき, 'accumulation, integration') + 度 (ど, 'degree'). The term is a modern technical coinage from the field of electronics.
