Technology giant has now invested $13 billion into Austin plant.
Samsung's plans of investing a substantial amount into a Texas plant to boost chip production has been approved by U.S. officials.
To keep up with the increasing demand for mobile devices ranging from smartphones and tablets, Samsung Electronics plans to make its Austin base into its central chip-making division through the $3.9 billion investment.
Talks have now been completed with Texas officials, with the production line expansion, as well as renovation given permission to commence.
Samsung's latest investment in the Texas plant brings the South Korean technology titan's total investment to over $13 billion since the plant came into fruition back in 1996.
Although it's currently battling Apple in court with several lawsuits, Samsung supplies memory chips for several products belonging to the former; it's the only company that can produce the amount Apple wishes in a specific time frame. It also produces chips for its own products such as the Galaxy lineup.
Samsung was recently named the worldwide cell phone market leader with a 29 percent share in 2012.
