Some of Taiwan\u2019s DRAM makers have reported record monthly sales for August, highlighting an increase in DRAM prices that could continue in the months ahead.The higher prices are unlikely to affect PC prices, thanks to the stiff competition among system vendors and makers of other types of components, such as microprocessors. But users who want some extra DRAM for their PCs could find themselves handing over a bit more money than before.Nanya Technology, Powerchip Semiconductor and ProMOS Technologies this week all reported record sales for August. The higher numbers stem partly from an increase in PC sales in some parts of the world. That increase drives up prices for DRAM, since most of the chips\u2014about three quarters of the global supply\u2014end up in PCs.Analysts say PC demand could stay robust for the next several months, as back-to-school demand and holiday demand are followed by the launch of Microsoft\u2019s new operating system, Vista. That could keep prices for DRAM high.The spot price Tuesday for the most widely used DRAM, 512-megabit double data rate, second generation (DDR2) chips, is around US$6, according to DRAMeXchange Technology. Crystal Lee, a memory chip industry analyst at ABN AMRO Asia in Taipei, forecasts that prices for the chips will remain at or near that level in coming months.Powerchip and ProMOS have been improving their ability to make chips using 90-nanometer production technology, which allows companies to make chips that are smaller, more powerful and more energy efficient. It can also help them reduce costs, because making smaller chips allows their production lines to churn out more chips using the same raw materials.Nanya\u2019s sales for August rose 32 percent to $6.62 billion new Taiwanese dollars, a new all-time high for the chip maker, the company said Tuesday.A day earlier, Powerchip Semiconductor said its sales for August rose to NT$8.03 billion (US$245 million), up from NT$4.45 billion in the same month last year. The figure was also 14 percent higher than in July, due to higher prices for the chips and increased output at factories. It was the company\u2019s fifth straight historical high.ProMOS\u2019s sales hit NT$6.01 billion last month, up from NT$2.53 billion during the same time a year ago, and 15 percent higher than July."DRAM contract and spot prices continued to rise last month, but we also benefited from our 90-nanometer process," said Ben Tseng, spokesman for ProMOS.-Dan Nystedt, IDG News Service (Taipei Bureau)Related Link:\n\nSun, Unisys Jointly File Suit Against DRAM MakersCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
