Samsung today revealed that it’s developed a 1GB DRAM for mobile devices that boasts a wide I/O interface and low power consumption to boot. The new mobile DRAM is capable of transmitting data at 12.8GB per second, an eightfold increase in bandwidth when compared to mobile DDR DRAM, and it’s made possible by the use of 512 pins for data input and output compared to the last-gen mobile DRAMs’ 32 pins. All this comes with a reduction in power consumption amounting to roughly 87 percent.
"Following the development of 4Gb LPDDR2 DRAM (low-power DDR2 dynamic random access memory) last year, our new mobile DRAM solution with a wide I/O interface represents a significant contribution to the advancement of high-performance mobile products," said Byungse So, senior VP of memory product planning and application engineering at Samsung Electronics.
"We will continue to aggressively expand our high-performance mobile memory product line to further propel the growth of the mobile industry," he continued.
Samsung’s next move is to provide 20nm-class 4Gb wide I/O mobile DRAM sometime in 2013.
It is right, although my mind does become befuddled when I think what practical uses a 12.8GB/sec transfer on a phone might be. Any suggestions?
so my girlfriend can play the new angry birds... in all seriousness that sounds like an insane amount of bandwidth for a smartphone.Maybe new mobile GPUs will need more bandwidth when they are used in tablets with the larger resolution
Considering most phone 3d "gpu"'s (not that i really consider a phones gpu worthy of the name gpu but that don't belong here) lacks dedicated memory it would soon become a bottleneck when for instance outputting 3d on a higher res external display. Other that that it seems like overkill for a phone when their cpu's have so limited I/O as well as computational power.
