Mohamed,

Value PC, i.e. dirt cheap, built with 64 or 128 MB of memory will be cheaper to build using RDRAM

I guess that explains the flood of Timna systems we have been seeing.

I always appreciate the firm grasp on reality demonstrated by some of the longs on this thread.

Hi Mohamed Saba; Re: "When the 256 Mbit memory devices become the primary size for memory, a Value PC, i.e. dirt cheap, built with 64 or 128 MB of memory will be cheaper to build using RDRAM. Only two 256 Mb chips are needed to make a 64 MB. Using SDRAM or DDR or whatever else requires the use of 8 chips for 256 MB. Thanks to the granularity of RDRAM."

Already, DDR chips are shipping on graphics cards in the x32 size. This gives DDR the ability to provide main memory for a PC with a width of x64 using only two chips. The x32 uses a TQFP-100 package. These are standard parts with Nvidia GeForce cards, though the graphics industry requires only the 128Mb parts. Here's a link for the Micron 4Mx32 DDR parts:

Hyundai's 4Mx32 DDR parts:

If the industry finds a need for 256Mb x32 DDR memory, the memory makers will make the parts. But 256Mb chips are kind of expensive right now. A cheaper solution would be 4 x16 128Mb parts.

RDRAM has almost no granularity advantage. And x64 DDR chips are in design.
