Samsung Producing Industry’s Highest Density Mobile DRAM, Using 30nm-class Technology
Samsung announced that it started the industry’s first production of four gigabit, low power double-data-rate 2 (LPDDR2) DRAM using 30 nanometer (nm) class technology earlier this month. The mobile DRAM chip will help the market to deliver thinner, lighter smartphones, tablets and other mobile devices, with longer battery life, at a level unachievable until now.
This new chip also combines high performance and energy efficiency. It delivers a data transmission speed of 1,066Mbps, which is more than double that of today’s MDDR, which operates between 333 to 400Mbps.
In addition, the chip enables a thinner, memory solution. When creating a 1GB (8Gb) LPDDR2 package with the previously highest density chips of 2Gb, four chips had to be stacked together. With the new 4Gb LPDDR2, stacking only two chips will achieve the same density, while providing a 20 percent package height reduction from 1.0mm to 0.8mm. It also consumes 25 percent less power.
