Samsung unveils the first 4.26GHz LPDDR4 chip with 12Gb capacity

Samsung Electronics has announced that it had begun mass production of LPDDR4 memory chips with 12Gb capacity. The new memory devices were designed for high-performance smartphones and tablets that require a lot of ultra-fast dynamic random access memory.

Samsung’s 12Gb LPDDR4 memory chip not only features unprecedented capacity – 12Gb, or 1.5GB – but also operates at 4266MHz effective clock-rate, which is considerably faster than the frequency of DDR4 modules for personal computers. The chip has 32-bit wide bus (two independent 16-bit busses) and has peak memory bandwidth of 17GB/s.

Samsung will sell its new 12Gb LPDDR4 memory devices in 3GB and 6GB packages, enabling smartphones and tablets with unprecedented amount of dynamic random access memory (DRAM).

The 12Gb LPDDR4 chips are made using a 20nm-class process technology and are considerably more energy-efficient than DDR3 or DDR4 chips used by personal computers thanks to 1.1V voltage (DDR4 has 1.2V voltage).


Samsung believes that in addition to smartphones and tablets, LPDDR4 memory will be used for ultra-slim PCs, digital appliances and automotive devices over time. Nowadays Apple MacBook notebooks use LPDDR3 memory instead of PC DRAM in a bid to prolong battery life.

“By initiating mass production of 12Gb LPDDR4 mobile DRAM in an extremely timely manner, we now are not only helping OEMs to accelerate their moves to the next generation of mobile devices, but also providing functionality that will give mobile consumers greatly enhanced user experiences,” said Joo Sun Choi, executive vice president of memory sales and marketing at Samsung Electronics. “Furthermore, we intend to closely collaborate with our global customers to move beyond premium smartphones and tablets in creating new digital markets that embrace the full potential of cutting-edge technologies like next-generation mobile DRAM.”

Samsung will begin to sell its 12Gb LPDDR4 memory chips in the coming months.
