The site's sources note Apple made the move to begin expelling Samsung from its supplier list in 2013. The company purchased mobile RAM for SK Hynix and Elpida Memory for the iPhone 5 while removing Samsung as a supplier.
Recently, Apple has been asking Elpida/Micron and SK Hynix to ramp up supplies of mobile RAM, but the two firms have been reluctant to increase their shipments as chip prices offered by Apple are less than desired. To ensure steady shipments of its new iPhones, Apple has had no choice but to add Samsung again into the supplier list for mobile RAM chip, added the sources.
Apple is widely expected to unveil the iPhone 6 on September 9th. Stay tuned to iClarified on Twitter, Facebook, Google+, or RSS for the latest!
