Chipmaker NVIDIA Corporation (NASDAQ:NVDA) has announced that it has suspended self-driving tests across the world. The announcement comes just a week after an Uber Technologies Inc autonomous car struck and killed one person crossing a street in Arizona.

Uber is among Nvidia’s partners and applies some of its self-driving technology. Nvidia’s shares sunk 7.8 percent at $225.52, losing more than $11 billion in market value.

The company’s shares have more than doubled in value in the one year on bets that the company is poised to become a leader in chips for data centres, driverless cars and artificial intelligence.

Uber halted North American tests of its autonomous cars after the fatal accident on March 18 in Tempe, Arizona. And Arizona has since suspended permission for Uber to test self-driving cars on public streets.

The California Department of Motor Vehicles recently said that Uber had indicated that it would not be renewing its current permit for testing autonomous cats in California.

In current terms, Uber has the permission to test autonomous cars on California public roads up to March 31.
