Apple warned by US lawmakers over using Chinese YMTC chips in new iPhone
- netsharc 4y agoI think I'm pretty tech savvy, I know it'd be possible there's some extraneous logic in these memory chips (beyond what's necessary for just making sure they store data properly), but it feels fantastical to think the logic would be able to control e.g. the WiFi chip to make a WiFi connection, and then open a connection to phone home (which I think is what Marco Rubio (R) et al are worried about?). What would be next, banning sand from China if they're used to make the silicon?
