Samsung Electronics Co Ltd said on Tuesday it has begun shipping its new class of 2GB DDR3 memory equipped with 40nm technology.

The new chip has 60 percent increase of productivity compared to its predecessor, which has 50nm of performance and its 2GB chip supports a data rate of up to 1.6Gbps at 1.35 volts. The chips will be produced in 16GB, 8GB, and 4GB RDIMMS for servers.

 “We see market adoption to DDR3 picking up steam and are accommodating that with early entry of 2Gb DDR3 using the most efficient DRAM manufacturing technology available today,” said Jim Elliott, Vice President, Memory Marketing, Samsung Semiconductor, Inc.

However, according to market research iSuppli, the firm projected DDR3 shipments to account for only 20 percent of the total DRAM in 2009, but its portion is expected to surge to 82 percent in 2012.

Seoul-based company will also produce UDIMMS (unregistered in-line memory modules) for workstations and desktop PCs along with SODIMMs for notebooks up to 4GB with its new chip.
