Latest rumors about the Apple iPhone 6S (and 6S PLUS) suggests that the U.S. based company will pack a 2GB LPDDR4 RAM memory inside of its Upcoming smartphone. Apple decided it shouldn't stick with LPDDR3, even if its 35% less expensive but it should expand its technology.
The Irony is that the 2GB LPDDR4 RAM chips that Apple will use will be made by Samsung and its partners (Micron-Elpida and Hynix). LPDDR4 memory is not only two times faster than LPDDR3, but also keeps power consumption the same while at it.
One of Samsung's manufacturing partners, Micron-Elpida, which experienced production issues and was reportedly behind schedule, but not any longer. The LPDDR4 chips should be ready for this year of the iPhone 6S.
