Do iphones really use 2+ old generation flash memory? I was surprised by this fact.
Does it not make a big difference these days if you're 2-3 generations behind Samsung?
- randyrand 4y agoFlash is not power intensive, for iphone workloads so it doesn’t matter. (ie not worth the cost) the density is good enough already.
- ulfw 4y agomaybe for the older SE line?
- wmf 4y agoAn iPhone using the latest and greatest flash chips has 512GB but with older generation flash it would be more like 128GB... which is the model most people buy. Of course that assumes YMTC can sell their "obsolete" flash at a lower cost per bit.
- fomine3 4y agoPerhaps they need to use old (lower density) NAND chip for lower capacity model, because fewer chips means less parallelism, thus low performance.
- adrian_b 4y agoAccording to the link from Semianalysis posted above, they are no longer behind Samsung, therefore they had to be hit urgently by US sanctions, otherwise they could have become the dominant producer of flash memories, like also Huawei could have become the dominant producer of smartphones, without the US sanctions.
- tooltalk 4y agoYMTC can certainly be the dominant player with mediocre components under Apple's China-first strategy.
