In the first quarter, said memory watcher DRAMeXchange, mobile DRAM revenues totalled $3.576 billion which is actually a small decline compared to the same quarter last year.
But despite that, mobile DRAM now accounts for 29.8 percent of total shipments worldwide and that figure will continue to increase.
Average selling prices for mobile DRAM are stable, while shipments grew as Samsung ramped up volumes by producing chips at 23 nanometres.
DRAMeXchange anticipates that prices will stay stable for the whole of the first half of this year. While next generation iPhones will use 2GB of mobile memory, prices will fall.
While the outlook is rosy for mobile DRAM, PC memory prices have fallen.
The major memory manufacturers are Samsung, SK Hynix and US firm Micron. Other much smaller players are Taiwanese companies Nanya and Winbond with the latter having a global market share of only one percent.
