Samsung has announced the industry’s first 8-gigabit low-profile double-data-rate 4 (LPDDR4) mobile DRAM chip, offering 1GB on a single die. The new LPDDR4 memory is said to provide 50 percent higher performance than current LPDDR3 offerings, with improved energy efficiency resulting in the chips using 40 percent less power than the previous generation, at 1.1 volts.
The chips are fabricated using “20nm-class” process, and combining four of these into a single package could offer up to 4GB of RAM on mobile devices, including smartphones, tablets, and notebooks. Mass production will begin sometime in early 2014, though Samsung hasn’t given an official time frame.
The announcement comes at an interesting time – Samsung has said that its next flagship, the Galaxy S5, will sport a 64-bit processor, and the inclusion of 4GB of RAM would put the 64-bit CPU to good use. The Galaxy Note 3 came with 3GB of RAM just two months after Samsung announced its 3GB LPDDR3 chip, so it wouldn’t be too far-fetched to think that 2014 will see smartphones encroaching personal computer territory even further with 4 gigabytes of memory, with the Galaxy S5 kicking off the trend.
