Will LDE Stand Between You And Your Next Smart Device?
By Tom Beckley
Compared to 28 nm, 20 nm potentially provides upwards of 20% improved performance, 30% power savings, and a 50% area reduction that allows designers to place between 8 billion and 12 billion transistors on a single system-on-chip. However, some technical challenges must be resolved before 20 nm is widely adopted.
