Samsung Electronics , the world's largest technology firm by revenue, raised the price of mobile processor supplied to Apple Inc. AAPL +0.14% by 20% recently, Chosun Ilbo reported Monday, citing a person familiar with negotiations between the two tech giants.

"Samsung Electronics recently asked Apple for a significant price raise in (the mobile processor known as) application processor," the person was quoted as saying in the report. "Apple first disapproved it, but finding no replacement supplier, it accepted the (increase.)"

The two firms have started to reflect the new supply price recently, the report added, citing the same person.

According to the report, Apple buys all APs used for production of iPhone and iPad from Samsung Electronics with the volume estimated to be 130 million units last year and more than 200 million units this year.

Samsung Electronics has a long-term contract to supply APs to Apple until 2014, the report added.

Samsung Electronics and Apple's South Korea office declined to comment on the report.
