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.
|Memory Maker||DIMM Sizes|
|Hitachi||64 MB, 128 MB, 256 MB|
|Hyundai||64 MB, 128 MB, 256 MB, 512 MB|
|IBM||64 MB, 128 MB, 256 MB, 512 MB|
|Infineon||64 MB, 128 MB, 256 MB, 512 MB|
|Micron||64 MB, 128 MB, 256 MB, 512 MB|
|Mitsubishi||64 MB, 128 MB, 256 MB|
|NEC||64 MB, 128 MB, 256 MB|
|Toshiba||64 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.
|Memory Type||Clock Specification||Price|
|PC100, 128 MB, CL2||100 MHz||$110|
|PC133, 128 MB, CL2||133 MHz||$116|
|PC200 aka PC1600, 128 MB, CL3||100 MHz DDR||$116|
|PC266 aka PC2100, 128 MB, CL2||133 MHz DDR||$125|
