Moore's Law

Definition

Moore's Law is the observation that the number of transistors on a microchip doubles approximately every two years, leading to an exponential increase in computing power and a decrease in relative cost per transistor. This principle not only drives the advancement of semiconductor technology but also affects the design and functionality of devices such as DRAM and flash memory, enabling them to become more efficient and powerful over time.

5 Must Know Facts For Your Next Test

1. Moore's Law has been a guiding principle in the semiconductor industry since Gordon Moore first made the observation in 1965.
