DDR-SDRAM Has Finally Arrived

DDR Standard In High-End 3D For A While

Of course, DDR-SDRAM is really not that new at all. It was pretty much introduced in the mainstream-PC arena by NVIDIA almost a year ago. NVIDIA's GeForce 3D-chip was one of the first PC-components that worked with DDR-SDRAM and since this time there is hardly any high-end 3D-card that could do without this memory type anymore. However, it took a while longer until all the specifications for DDR-SDRAM as main memory were finalized.

The Memory Industry Gives Broad Support

Due to its free and open specification , DDR-SDRAM enjoys a broad support in the memory industry. Right now we know of eight different memory makers that are already producing DDR-SDRAM DIMMs in all kinds of sizes.

Hyundai64 MB, 128 MB, 256 MB, 512 MB
IBM64 MB, 128 MB, 256 MB, 512 MB
Infineon64 MB, 128 MB, 256 MB, 512 MB
Micron64 MB, 128 MB, 256 MB, 512 MB
Mitsubishi64 MB, 128 MB, 256 MB
NEC64 MB, 128 MB, 256 MB
Toshiba64 MB, 128 MB, 256 MB

DDR-SDRAM gets manufactured in a very similar way as normal SDRAM, which is why there won't be much of a price premium for the new memory type.
