Samsung reportedly set to supply Apple with new memory chips

Samsung has entered into an agreement with Apple to supply the company with new 20nm LPDDR4 DRAM chips. The deal would see Samsung fulfill Apple's demand for memory chips for the next iPhone. According to the Korea Times report:

The agreement comes a few months after Samsung, the world's biggest memory chip supplier, began mass production of the next generation memory chip ― the 8-Gigabit LPDDR4 (low power double data rate) mobile DRAM with 20 nanometers. The so-called LPDDR memory, the most used in mobile devices, is poised to enable a new technological leap for premium smartphones.

Sources familiar with the matter revealed to the publication that not only will Samsung be shipping out components to Apple, but that the company will also be installing the in-house DRAM chips inside the Galaxy S6. This deal would also join the order for Samsung to produce the A9 chipset for Apple.

  • So apple is gonna jump from 1 Gb if ram to 8? Sent from the iMore App
  • That was gigabit, as in speed not size... I think. Sent from the iMore App
  • So what does that mean then? I can't seem to find that anywhere online. Sent from the iMore App
  • It's 8 gigaBIT DRAM. What you have inside current iPhones are 1 gigaBYTE of DRAM, and a low power double date rate version 3 (LPDDR3) of it. Not quite sure if the 2, 3, or 4 in the DDR1, 2, 3, 4, mean versions or double data rate, quad data rate etc, actually. I just think of it as 4th version of a double data rate design, the details of which we shouldn't get into. 1 byte has 8 bits. So an 8 gigabit DRAM chip is equivalent to 1 gigabyte of memory. How much is actually in the 2015 iPhone models is a guessing game. Since these LPDDR4 chips have twice the transistor density as LPDDR3 chips currently used in iPhones, it may indicate that the 2015 iPhone models will have 2 GBytes of DRAM memory.
