On the subject of mobile RAM, capacity is normally what pops to mind first while we overlook speed and gear consumption, but Samsung’s latest delivery is well worth the extra attention. Earlier this month, said Korean giant started producing 30nm 4Gb 1066Mbps LPDDR2 (or just Mobile DDR2) chips, so one can phase out its 40nm ones that topped 2Gb at a 800Mbps transmission rate. To position it in perspective, a 40nm 1GB package includes four 2Gb chips, whereas the hot 30nm one will only need two 4Gb chips, thus reducing the package thickness by 20 percent (all the way down to 0.8mm) and tool consumption by 25 percent. It’s hard to inform after we’ll start seeing these bits of silicon entering the buyer market, but Samsung’s already stamping out 1GB modules this month, with a 2GB version to follow next month. Oh yes, we’re definitely liking the sound of 2GB RAM for cellphones.
