We already reported before that Samsung Mobile has already began mass production of a 20nm 4GB LPDDR4 Mobile DRAM memory chips. Using the 20nm manufacturing process, these LPDDR4 chips will be reportedly 50% faster than the fastest LPDDR3 memory chips on the market and consuming 40% less power (1.1 volts) too. These chips will be available by Late 2015.
Today, some reports comes from South Korea confirms that the upcoming Samsung Galaxy Note 5 phablet will pack the same 4GB LPDDR4 RAM chip we mentioned above, which brings the phablets performance to a whole new look.
Also confirmed is the fact that the Note 5 will use Samsung's own Exynos 7422 chipset, the company's first to be a true single-chip solution. This means one package will incorporate the octa-core CPU, the GPU, the RAM, the storage, as well as the Shannon 333 LTE modem.
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.
