Soaring sales of the iPhone and iPad lines have made Apple the world's top buyer of semiconductors.
Research firm IHS iSuppli said in a recent report that Apple has now overtaken HP as the top purchaser of semiconductors among all OEMS.
Apple is expected to spend $22.4bn on semiconductors this year, followed by HP with $14.8bn and Samsung with $14.3bn.
Much of the growth in Apple's spending has been attributed to huge demand for the company's mobile devices.
IHS iSuppli analyst Wenlie Ye told V3.co.uk that strong sales of the iOS platform are leading Apple to purchase greater volumes of the NAND flash memory chips used for storage.
"Prior to its iPod era Apple was looked at as a computer company like HP or Dell," said Ye. "But now almost 60 per cent of its purchasing is focused on the wireless field."
Apple sold 18.65 million iPhones, 9.02 million iPods and 4.69 million iPads in its most recent financial quarter, according to the company's figures.
Ye expects the strong sales to continue to drive Apple's semiconductor spending in the coming years, perhaps increasing the firm's current 30 per cent share of total flash memory consumption.
The bulk of HP's purchases, meanwhile, come from DRAM memory chips for PCs rather than NAND flash.
