What other IC Chips cannot be separated?
I know that on an iPhone several IC Chips cannot be separated and need to stay together for the iPhone to function properly and if you were to replace any of them they need to be reprogrammed which not may people can do. I know that on the iPhone SE the Apple A9, Qualcomm MDM9625M, and the Toshiba NAND Flash are tied together and can't be separated. Are there any other chips that are also tied together with these?
Is this a good question?
