DRAMeXchange today reported the results of worldwide DRAM memory shipments in October 2002. Apparently, global output of DRAM increased 8% in October compared to September due to stronger demand on personal computers. The shares of different types of memory available on the market clearly represent the well-known trend: DDR SDRAM will dominate and will not leave any chances for the rest types of DRAM.

Memory makers continue to deploy their DDR SDRAM manufacturing capacities and upgrade the equipment on the fabs that still produce SDR SDRAM. No one wants to invest in the dying RDRAM and those, who still manufacture it have to lower the amount of chips since the demand is very weak and will be even lower later.

At the moment DDR SDRAM occupies 57.15% of the DRAM market, an increase from 45.52% in August, SDRAM - 39.08%, a decrease from 49.94% in August, and RDRAM can boast only with 3.77%, 0.77% lower than in August. In October were shipped 211.93 million of 128Mb equivalent DDR SDRAM chips, about 144.94 million of 128Mb equivalent SDRAM chips and 13.99 million of 128Mb equivalent RDRAM devices. Just for comparison: in August memory makers sold 155.9, 171.08 million and 15.55 million of 128Mb equivalent DDR, SDR and RDRAM chips respectively.

The demand on DDR SDRAM will become even higher when Intel starts to unveil its dual-channel DDR SDRAM-supporting platforms massively later this year. SDRAM will remain in the low-end segment of the market for some time, but will eventually leave the PC market, just like RDRAM.
