Where Wizards Stay Up Late: The Origins Of The Internet
The Idea Factory: Bell Labs and the Great Age of American Innovation
The Chip: How Two Americans Invented the Microchip and Launched a Revolution
That last one is a little dry, I still found it interesting. It's about Jack Kilby and Robert Noyce. It's currently available for sale for $1.99 on the Kindle.
I'd add Eccentric Orbits and Skunk Works, both of which are about other fields (satcom and aero, respectively), but have similar themes of innovation and its mother, necessity. (And mother-in-law, politics.)
Along those lines, a personal favorite is Empires of Light, covering the race for electrification and lighting. It critically includes the role of George Westinghouse, which a lot of books leave out (typically focusing more on Tesla & Edison instead).
