South Korea's Samsung Electronics Co. has resumed its supply of dynamic random access memory products to its rival U.S. Apple Inc. for the iPhone 6 to be released next month, industry sources said Wednesday, in a sign of reconciliation after a series of patent disputes.

The world's No. 1 maker of smartphones recently has been providing its 20-nano level mobile DRAM for Apple's new iPhone, the sources said. The U.S. tech player has been resorting to SK hynix Inc. and Micron Technology Inc. for the chips needed in the iPhone 5 and iPhone 5s.

The sources said the latest move is significant in that it came only a few weeks after Samsung said earlier this month it has agreed with Apple to end ongoing patent lawsuits outside of the United States.

Samsung and Apple have been engaged in legal wrangling in the U.S. since April 2011, accusing each other of copying patented technologies in their smart devices. Since then, the dispute had spread to South Korea, Japan, Germany, Italy, the Netherlands, Britain, France and Australia.

The move will also boost Samsung's semiconductor division's earnings, coupled with the rising price of DRAMs in the global market, they added.

Samsung accounted for 37 percent of the world's DRAM market in the first quarter, data compiled by IHS iSuppli showed. SK hynix and Micron Technology held comparable figures of 27.8 percent and 26.9 percent, respectively. (Yonhap)
