Samsung’s DRAM memory chips, alpha microprocessors, graphics, and flash memory chips are all under investigation, Reuters reports. The case was sparked by a complaint made by Toshiba on April 22.
Apple has a close relationship with Samsung, in which it once invested $100 million in order to help maintain a steady flow of LCD screens.
A Samsung spokesman told Reuters that the company wants to make an amicable settlement with Toshiba, but would consider a legal response if this wasn’t possible.
The accusations come as Samsung announces plans to invest $427 million in next-generation semiconductor production lines this year. It’s an attempt to meet expected increased demand in the second half of the year.
