Apple has confirmed it bought flash storage technology maker Anobit, whose chips are already used in the iPad.
Israeli media reported in December that Apple bought Anobit for as much as $500 million, its first acquisition of an Israeli company.
Apple declined to comment at the time.
"Yes we did buy Anobit," Apple spokesman Alan Hely said, declining to elaborate.
"Apple buys smaller technology companies from time to time and we generally do not discuss our purpose or plans."
Anobit has developed a chip that enhances flash drive performance through signal processing.
The chip is already incorporated in Apple devices such as the iPhone, iPad and the MacBook Air.
The Calcalist financial daily reported last month that Apple, among one of the largest buyers of flash memory, was interested in Anobit's technology to increase and enhance the memory volume and performance of its devices.
The chip may as much as double the memory volume in the new iPads and MacBooks.
Anobit has raised $76 million from Battery Ventures, Pitango Venture Capital and Intel Capital since it was founded in 2006.
