It seems that Apple has become a very important income source for Samsung as the American company keeps giving contracts the the Korean tech giant.
SK Hynix and Toshiba have both experienced lower-than-expected yield rates for their 3D NAND technologies resulting in fewer supplies for Apple’s 2017 series of iPhones, according to Digitimes.
In this context, Apple turned to Samsung for more NAND chip supplies for its upcoming phones, including the iPhone 8. It seems that Samsung has relatively stable yield rates for 3D NAND technology and has scaled up its output of 3D NAND chips.
In case you forgot, Samsung is the sole OLED panels that will equip the new iPhones that will be launched in the fall. Apple made Samsung its OLED supplier for the next two years.
