Samsung Begins Producing Industry's First Four Gigabit LPDDR3 Mobile DRAM
According to Samsung, the major upside with these mobile chips is that they offer comparable performance to standard DRAM found in desktop and laptop computers. The speedy chips transmit data at up to 2,133 megabits per second (Mbps) per pin, which is more than double the performance 800Mbps LPDDR2. Samsung says it's possible to transmit three Full HD videos totaling 17GB (collectively) in just one second over the new chip embedded in a mobile device.
"By providing the most efficient next-generation mobile memory with a very large data capacity, we are now enabling OEMs to introduce even more innovative designs in the marketplace," said Young-Hyun Jun, executive vice president, memory sales & marketing, Samsung Electronics. "Our 20nm-class four gigabit mobile DRAM provides another example of our ability to deliver well-differentiated, high-performance, high-density memory to customers in a timely manner."
Compared to 30nm-class LPDDR3 DRAM, Samsung says devices that use the new 20nm-class chips offer a 30 percent improvement in performance and 20 percent savings in power consumption. At the same time, Samsung says OEMs can have a 2GB package that includes four of Samsung's new chips in a single package that meets the memory package height of 0.8mm, so the chips won't affect the size of upcoming devices.
