Samsung is reportedly buying more memory products from outside of their own influence, from places like Elpida Memory and NAND flash and eMMC devices from Toshiba. Why? Because they're selling so many smartphones that they can't produce enough memory from their own factories, they're having to buy it from others.
DigiTimes is behind the report, where industry sources have claimed "Samsung's own supply of memory products is already falling short of demand, including that for its Galaxy-series smartphones and tablets". This problem is also set to expand past Samsung, because any shortage in either DRAM or NAND flash will affect the global balance of both products.
But remember this, Samsung are the ones that make the most DRAM and NAND flash - so if they're running short on supply, what happens next?
