14 DAY TRIAL // The most widespread type of memory is SDRAM (synchronous DRAM), which processes data at 226 - 400 MBps.
This type of memory is mostly preferred by the mobile system producers, and the specialists forecast that the new technology will prevail beginning from 2006.
Even though DDR2 is not yet broadly used, the successor of this technology has already been presented by Samsung, a DDR3 prototype being displayed 3 weeks ago. Based on the 80 nanometer technology, its power consumption is reduced by 40% compared to DDR2.
Still, with DDR3 being in a mere prototype stage, the producers are making the first steps for largely adopting the DDR2 standard, and its dramatic price decrease is only accelerating the process.
The DDR2 module manufacturers still maintain the level at a 30% of the full production capacity, but there is an ascending trend, the production of DDR1 and DDR2 being expected to level out by June.
DDR2 frequency varies from 400 to 800 MHz (the latter due for the end of the year). It's likely that DDR2-800 will be designed to ease the transition to DDR3-800. The manufacturers planned the transition better than the one to DDR2, allowing a longer adapting period.
