The transistor density of a monolithic integrated circuit refers to the number of individual transistors that can be packed into a set amount of area.
The real or effective transistor density of a die can be calculated through:
Although the effective transistor density provides the average density of the transistor for a particular real-world product, it is not possible to compare different product families in such a way due to numerous reasons, including:
- Interconnect consideration
- Performance consideration
- Std. cell vs Full custom
- Ratio of components on-die
