Samsung announced today that it started the industry?s first
production of four gigabit (Gb), low power double-data-rate 2
(LPDDR2) DRAM using 30 nanometer (nm) class technology earlier this
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.
"Mass production of 4Gb LPDDR2 is a tremendous advancement for the
mobile industry, one that will enable our OEM customers to move
quickly in launching better differentiated high-performance mobile
devices into the market," said Wanhoon Hong, executive vice
president, memory sales & marketing, Samsung Electronics.
Samsung developed the 4Gb LPDDR2 DRAM in December of last year and
began mass producing it earlier this month. Compared to the previous
40nm-class 2Gb LPDDR2 DRAM, the 30nm-class 4Gb LPDDR2 DRAM increases
productivity by 60 percent.
The 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.
Samsung plans to produce the 4Gb LPDDR2 chip based 1GB (8Gb) packages
beginning this month, and plans to produce 2GB (16Gb) packages
consisting of four 4Gb devices next month.
Samsung expects that the new 4Gb LPDDR2 based solutions will benefit
mobile device makers greatly as they launch competitive products
using dual-core processors, which require mobile memory with higher
performance and density.
According to iSuppli, shipments of mid to high-end smartphones will
increase at about an 18 percent annual rate, from 2009 to 2014. This
is expected to lead to dramatic expansion in the use of mobile DRAM,
which iSuppli projected will grow at an annual rate of 64 percent
during the same period.
