Apple has reportedly tried to reduce its reliance on rival Samsung by cutting its memory chip order for its new iPhone.
Samsung has been a core supplier of Apple, producing micro processors, flat screens and memory chips for the iPhone, iPad and iPod.
According to sources, Apple has been cutting its orders from Samsung as it tries to diversify its lines of supply for memory chips, although Samsung remains on the list of initial suppliers for the first batch of the new iPhone.
Apple have apparently instead picked Japan's Toshiba Corp, Elpida Memory and Korea's SK Hynix to supply DRAM and NAND chips.
There had been speculation that Samsung had been dropped from list of memory chip suppliers for the iPhone but sources have confirmed that Samsung is still on the list
A source told Reuters: "Samsung is still in the list of initial memory chip suppliers (for new iPhones). But Apple orders have been trending down and Samsung is making up for the reduced order from others, notably Samsung's handset business."
The source denied claims that the reduced orders from Apple were due to a souring relationship between the two companies who are locked in patent disputes spanning four continents.
The decision has apparently come as Apple looks to widen its supply chain. The firm often faces a supply crunch when a new product is launched, triggering a consumer stampede.
It comes on the day that a judge in the United States has turned down Apple's request to reschedule a hearing on September 20 that could see the ban on Samsung's Galaxy Tab 10.1 lifted
Judge Lucy Koh will hear Samsung's motion to dissolve the preliminary injunction against the Galaxy Tab 10.1 in California but Apple wanted to reschedule the hearing for December.
Apple argued that the judge would hear Samsung's motion to lift the injunction three months before hearing Apple's request to ban eight Samsung devices which is scheduled for December 6.
If the judge lists the ban on the Galaxy Tab 10.1 Samsung may be able to sell the product in the run up to Christmas.
