After a number of 128GB iPhone 6 Plus owners who had installed a large number of apps on their devices complained about unexpected crashes and reboots, a report from South Korea suggested Apple might considering a recall for the device, as the bug might be caused by a certain type of memory modules. The report has been refuted since, with 9to5Mac saying Apple is aware of the limited issue, and Digitimes adding that memory makers said that particular memory isn’t at fault for crashes.
But now, Business Korea said on Friday that Apple is apparently ready to replace that particular memory type (triple-level cell NAND or TLC NAND) from 128GB iPhone 6 Plus and 64GB iPhone 6 units in order to avoid similar issues in the future. Apparently, in addition to some 128GB iPhone 6 Plus owners, some 64GB iPhone 6 buyers have also experienced similar crashes.
Apple is reportedly planning to use multi-level cell NAND in these models, but existing units will supposedly be fixed with the upcoming iOS 8.1.1 update. Apparently, the memory controller IC, which is made by Apple’s Anobit division (a company purchased in 2011), is to blame.
Business Korea further adds that TLC NAND can store more data per cell, but it’s also slower than MLC and SLC (single-level cell), and cheaper, which could be one reason Apple used it in its high-capacity iPhones.
Apple has yet to officially comment on this particular iPhone 6 / iPhone 6 Plus issue.
