This year 1GB of memory will become quite common for notebooks, according to DRAMeXchange.
DRAM modules are expected to see the biggest growth ratio among the various NB components after the Vista launch. From the official figures from Microsoft's website, the minimum DRAM requirement in respectively running the Home Basic and Home Premium editions stands at 512 MB and 1GB. In contrast to the minimum requirement of 256MB for Windows XP and Windows 2000, twice as much DRAM memory is needed. According to data compiled by DRAMeXchange, the average DRAM content per box for each NB in 4Q06 is roughly 826MB. By May, 2007, it is projected to surpass the 1GB threshold reaching 1019 MB. The average content per box for 2007 will approximately hit the 1058MB level. In general, the DRAM demand in NBs is expected to significantly grow, as the usage of Vista becomes more widespread.
