2GB DDR2 modules may not be mainstream until 2008
While 1Gbit DDR2 chips are still available in very limited quantities in the open market, 2GB DDR2 desktop modules may not go mainstream until 2008, according to industry sources. Memory module houses currently put more focus on 2x1GB dual-channel solutions, which consist of two identical 1GB modules, typically using 512Mbit (64×8) chips, offering them at lower prices than “pure” 2GB modules utilizing 1Gbit (128×8) parts, with the price gap exceeding 50% in some cases.
1Gbit DDR2 chips are currently traded in very low volume in the spot and contract markets, representing less than 1% of trading volumes, said DRAMeXchange industry research division director Joyce Yang. Seeing only Samsung offering 1Gbit DDR2 chips, DRAMeXchange expects other DRAM makers to follow when their 70nm production processes reach mature yields, she added. According to DRAMeXchange, DDR2-800 modules will go mainstream in the second half of 2007 while 2GB DDR2 modules will likely have to wait until 2008.
