The majority of the sizable order is expected to be applied toward the 16-gigabit NAND, signaling that a 32-gigabyte iPhone is in the works to debut in June, said Daniel Amir, a Lazard Capital Markets analyst.

An order of 100 million 16-gigabit chips, for example, could produce roughly 12 million of Apple's 16GB iPhones, far more than the 7 million iPhones Wall Street expects Apple to make in the second quarter. But the same order of 100 million chips could produce roughly 6 million Apple 32GB iPhones.
