Embedded DRAM has three major problems - assuming "conventional" DRAM. 1. It is too slow. Current SRAM technology can run at speeds up to 500 MHz or more - Only RAMBUS-type of DRAMS can come close to this. Paul, There is a simple trick to speed up DRAM page hits. Enhanced Memory Systems sells EDRAM which reads out the entire row into SRAM when the page is opened. All page hits are then serviced at SRAM speed. There are quite a few other tricks which could be done with embedded DRAM to enhance performance. The first CPU manufacturer to do this will see remarkable performance gains. DRAM densities are much higher than SRAM densities, so the area tradeoff would favor embedded DRAM rather over huge caches (in SP systems.) Scumbria

Intel has an investment of about $250,000,000 in a Samsung Memory Fab in Texas. My guess is that Intel wanted to "help" Samsung see their way clear to supporting RAMBUS memory - which they have. Samsung also is pursuing non-RAMBUS advanced memory technology. Paul, So I take it that Intel has something up their sleeves with DRAM. I hate to admit it, but Intel is acting awfully sharp under the leadership of Barrett. Scumbria
