RE: <Also note that the same Samsung web page that advertises RDRAM, also advertises 32M DDR SGRAM. Look just under the "DRAM" sign: usa.samsungsemi.com; I wonder if that is what nVidia will use with their GeFOrce graphics? I heard that they support DDR.

Another example of a great, cheap, x32 SDRAM. September 20, 1999 32-Mbit SGRAM targets 3-D graphics SAN JOSE, CALIF. - Samsung Semiconductor Inc.'s 222-MHz KM4132G112, a 32-Mbit synchronous-graphics RAM for 3-D graphics and networking applications, boasts what the company said is a gain of up to 55 percent in memory performance compared with best-in-class systems. Avo Kanadjian, senior vice president of memory marketing, said the device, organized as 2M x 32, is faster than 1M x 16 and 2M x 32 SDRAMs on the market. It offers an alternative to technologies including Rambus and double-data-rate DRAM for graphics applications, he said. On a 64-bit bus, the SGRAM provides 8 bytes at 222 MHz, delivering 1.8 Gbytes/second. On a 128-bit bus, it provides 16 bytes at the same frequency, at 3.5 Gbytes/s. "Bandwidth [is] a critical issue in graphics memory," Kanadjian said. Samples are available now, with production quantities due this month. The KM4132G112 is priced at $8 in lots of 1,000. techweb.com The above pricing is comparable to 64M parts which are usually x8, but each chip has half the memory and something like 8.8 times the bandwidth. Here is a reference for 8Mx8 pricing: contract prices for the 8-Mbit x 8 PC100 SDRAM have rebounded to the $8 to $8.50 range techweb.com Interesting historical note: Here is an announcement of x32 SDRAM/SGRAM parts from back in 1994, that also talks about early SDRAM and RDRAM stuff: techweb.com -- Carl P.S. I would also like to correct an assumption in the post that this linked to. FCRAM is not a variety of VCRAM. I should do some research on VCRAM, though.
