First commerical 3D chip targets tweens

Start-up company Matrix Semiconductor has a customer for its unusual 3D memory chips. And no, it's not a major high-end computing vendor, but rather a toy company, Mattel. It's for permanently storing cartoons on a media player called the Mattel Juice Box aimed at "tweens" (8-12 years old). While the player received an upgraded version of the chip weeks ago, analysts from Chipworks seem to have just got their hands on it recently.
