The Samsung 3GB LPDDR3 mobile DRAM uses six of the industry’s smallest 20-nanometer (nm) class* four gigabit (Gb) LPDDR3 chips, in a symmetrical structure of two sets of three chips stacked in a single package only 0.8 millimeters high. With a full line-up of package dimensions, Samsung’s new ultra-slim memory solutions will enable thinner smartphone designs and allow for additional battery space, while offering a data transfer speed of up to 2,133 megabits per second (Mbps) per pin.
“Three gigabyte mobile DRAM will be adopted in the most up-to-date, high-end smartphones starting in the second half of this year ? an initial adoption that will expand to most high-end smartphones worldwide next year,” said
With the increased mobile DRAM capacity, users can enjoy seamless high-quality, Full HD video playback and faster multitasking on their smartphones. Also, the new LPDDR3 speed up data downloading and is able to offer full support for LTE-A (LTE Advanced) service, a next-generation mobile telecommunication standard.
Samsung’s 3GB LPDDR3 DRAM connects with a mobile application processor using two symmetrical data transfer channels, each connected to a 1.5GB storage part. Though asymmetric data flow can cause sharp performance dips at certain settings, the symmetrical structure avoids such issues, while maximizing system level performance.
