Samsung is rolling out the industry’s first production of 4-Gbit LPDDR2 DRAM chips using 30-nm class technology to enable thinner, lighter smart phones, tablets, and other mobile devices with longer battery life.

Samsung is rolling out the industry’s first production of 4-Gbit, low-power double-data-rate 2 (LPDDR2) DRAM chips using 30-nm class technology (see the figure). As expected, the devices will inevitably enable thinner, lighter smart phones, tablets, and other mobile devices with longer battery life. According to the company, the 30-nm class 4-Gbit LPDDR2 DRAM increases productivity by 60% over previous 40-nm, 2-Gbit devices. It also delivers a data transmission speed of 1066 Mbits/s, more than double that of today’s memories operating from 333 to 400 Mbits/s. Samsung plans to produce the 4-Gbit LPDDR2 chip in 1-Gbyte (8-Gbit) packages beginning this month and plans to produce 2-Gbyte (16-Gbit) packages consisting of four 4-Gbit devices soon thereafter.
