Apple taps Samsung for the processors inside its popular portable devices, and it's apparently fond of the company's employees as well.
The Wall Street Journal notes that Jim Mergard, who joined Samsung last June to be its chief system architect, has left to go work at Apple. Before Samsung, Mergard spent 16 years at Advanced Micro Devices, where he was a vice president and chief engineer.

In early August Advanced Micro Devicesto be its corporate vice president and chief architect, reporting to former Apple hardware chief Mark Papermaster. The month before it was AMD chip designer John Bruno, to go to Apple as a system architect.

Besides screens and system memory, Apple also uses the company's processors -- that includes the A6, the custom ARM-based processor inside the iPhone 5, which Apple promotes as one of its headlining features. Apple designs those chips, while Samsung manufactures them.
