As the saying goes, everything's bigger in Texas, and that includes Texas Instruments' (TI) share of the semiconductor market. The Dallas-based firm announced today that it will pay $6.5 billion for National Semiconductor. With the acquisition complete, National will become a branch of TI's analog segment, which is now positioned to make up 50 percent of the company's revenue. According to a joint press release, TI held the biggest chunk of the analog semiconductor market in 2010 at 14 percent, and with the new addition that number's bound to get even bigger. Full PR after the break.
