Shortage of Xbox 360s due to memory chips?

If you've been trying without success to find an Xbox 360 since November, you might want to blame the shortage of Microsoft's new video game console on one of the companies making chips for the machines.

According to the San Jose Mercury News' Dean Takahashi, Infineon, one of the two companies manufacturing chips for the new console, has been unable to keep up with demand. And because of the chip shortage, Takahashi writes, Microsoft hasn't been able to satisfy the Xbox hunger.

The new Xbox debuted last November and quickly sold out in stores across North America. Microsoft has said repeatedly that it plans to replenish stocks soon and that its ability to do so will be helped by the addition of a new Chinese factory run by the Canadian company, Celestica.
