Wily, <Isn't it testimony to the fact of embedded memory's advantages that Intel makes a giant chip for servers (Xeon, 500MHz) with 2MBytes of embedded SRAM, that costs about 5X as much as its counterpart without the large cache?> There's a big difference. Xeon's SRAM is a cache. Embedded memory is a replacement for DRAM (at least in the way we're talking about it). Xeon is intended to go into servers which hold gigabytes of main memory. If fast embedded memory like OUM is going to be used in Xeon-based servers, it'll either have to replace SRAM in the cache, or just function as yet another layer of cache between the SRAM and the DRAM. There's no way that embedded memory can take the place of gigabytes of main memory. Now, for desktop systems that don't require gigabytes of memory, embedded memory shows a lot of promise, especially in systems which integrate just about everything but the kitchen sink. But embedded memory, even that based on OUM, will still have one big weakness: the lack of expandability. That's one reason why I don't think DRAM will go away for a long time. Tenchusatsu
