Samsung's new chip paves way for 4GB RAM phones
As the battle for smartphone hardware specifications reaches the next level, Samsung is gearing up for devices powered by 4GB RAM. Expect to see flagship smartphones from Samsung and others to come with 4GB RAM in 2015.
The South Korean electronics giant has started to mass produce 8 gigabit (Gb) low power double data rate 4 (LPDDR4) mobile DRAM based on 20-nanometer (nm) process technology paving way for 4GB mobile RAM. According to the company, the new 8Gb LPDDR4 chip allows a 4 gigabyte (GB) LPDDR4 package to be created.
In a post on its official blog, Samsung states that due to an I/O (Input/Output) data rate of up to 3,200 megabits per second (Mbps), which is two times faster than a typical DDR3 DRAM used in PCs, the new RAM module is capable of supporting UHD (4K) video recording and playback and continuous shooting of high-resolution images with over 20MP.
The new 20nm 8Gb LPDDR4 offers twice the performance and density compared to 4Gb LPDDR3 which was based on 20nm-class process technology, it added.
The new mobile memory chip is also more power efficient as its operating voltage was reduced to 1.1V from that of LPDDR3 memory chips, which makes the new Samsung chip the lowest power memory solution available for large-screen smartphones and tablets, and high-performance network systems, as per the company.
More memory would also mean that phones with 64-bit chips would be able to manage RAM in a better manner.
Samsung has already started providing 2GB LPDDR4 and 3GB LPDDR4 DRAM packages based on 8Gb and 6Gb LPDDR4 dies, respectively, and will provide 4GB LPDDR4 packages in early 2015.
