Reports suggest that Apple has doubled the amount of memory it is ordering from Samsung Electronics to meet the demand for Apple iPhone 3Gs when they launch on July 11.

Apple has ordered a huge batch of the Samsung 8GB NAND Flash chips it uses in the iPhone. Samsung may not now be able to meet supplies to other companies, according to the report on DigiTimes.

The total number of 8GB chips ordered has reached 50 million, a 100 percent increase on the 25 million chips previously reported.

Because of the scale of the order, Samsung Electronics may not be able to meet supplies to other customers during July. According to sources within the company Samsung has said it will sharply cut supply to other customers.
