Samsung was Apple’s main supplier for the iPhones from the very beginning, making the A-series processors and supplying both NAND flash and DRAM memory chips. But Samsung started to supply less components to Apple since 2011, coincidentally when Apple sued Samsung for patent infringement. The South Korean company now only supplied DRAM chips for the iPhone 7, according to a teardown by iFixit.
But that trial is finally wrapping up, with the U.S. Supreme Court ruling in favor with the South Korean company last week, just when Samsung is set to be iPhone’s main supplier once again next year.
Some of the most expensive components of an iPhone are the display panel and memory chips (both NAND flash and DRAM combined). In the iPhone 7 (32GB), these components together are worth over a quarter of the total bill of materials ($219.80), according to data from IHS Markit. Reports say Samsung will provide OLED display panels for at least one of the next iPhones, as well as NAND flash memory chips again. Adding DRAM chips into the mix will make Samsung the main supplier out of hundreds of companies.
