Samsung this week unveiled what it claims is the industry's first monolithic four gigabit (Gb), low power double-data rate 2 (LPDDR2) DRAM built on a 30nm manufacturing process. The new chip is specifically intended for high-end smartphones and tablets
"The mobile device market is gaining momentum with the advent of tablet PCs, which is adding significantly to the already surging smartphone segment," said Jun-Young Jeon, vice president, memory product planning team, Samsung Electronics. "Samsung will work closely with mobile device designers to bring high-performance, high-density mobile solutions to market as rapidly as possible."
According to Samsung, its new LPDDR2 part can transfer up to 1,066Mbps, offering similar performance to desktop memory. It's also more than twice as fast as previous mobile DRAM technology.
Samsung said it will begin sampling 8Gb (1GB) LPDDR2 DRAM this month by stacking two 4Gb chips in a single package, whereas previous 8Gb LPDDR2 DRAM used four 2Gb chips. The upshot here is a 20 percent height reduction, which should help result in slimmer mobile devices, and 25 percent less power consumption.
