Samsung Electronics has announced they have developed the industry’s first 8 gigabit (Gb) or 1 Gigabyte (1GB) LPDDR4 DRAM for mobile devices such as smartphones and tablets. This will provide the highest level of density, performance and energy efficiency for mobile memory applications, enabling end users to have faster, more responsive applications, more advanced features, and higher resolution displays while maximizing battery life, said Samsung.
Regarding the new DDR4 RAM, Young-Hyun Jun, executive vice president, memory sales & marketing, Samsung Electronics, said
This next-generation LPDDR4 DRAM will contribute significantly to faster growth of the global mobile DRAM market, which will soon comprise the largest share of the entire DRAM market. We will continue introducing the most advanced mobile DRAM one step ahead of the rest of the industry so that global OEMs can launch innovative mobile devices with exceptional user convenience in the timeliest manner.
Features of Samsung’s new high-speed 8Gb LPDDR4 mobile DRAM
- Fabricated on 20-nanometer (nm) class process technology
- 1 gigabyte (GB) on a single die, which is the largest density available for DRAM components today
- With four of the 8Gb chips, a single 4GB LPDDR4 package can provide the highest level of performance
- Uses a Low Voltage Swing Terminated Logic (LVSTL) I/O interface, now a standard specification for LPDDR4 DRAM, proposed by Samsung
- Data transfer rate of 3,200 megabits per second (Mbps) per pin, twice that of the 20nm-class LPDDR3 DRAM
- 50 percent higher performance than the fastest LPDDR3 or DDR3 memory
- Consumes approximately 40 percent less energy at 1.1 volts.
Samsung unveiled the 3GB LPDDR3 (6Gb) package solution earlier this year, which is being used in the Note 3. It will start mass producing new 8Gb LPDDR4 DRAM in 2014. Hope we can expect 4GB of LPDDR4 RAM solution in next-generation mobile devices from Samsung next year. Probably in the Note 4?
