News Remember the future? It's MRAM, not DDR

ipKonfig.com has some thoughts on future memory technology:

MRAM is not just newer and faster memory, it's a whole new ball game. Processors, bridges, and software will have to adjust when memory is non-volatile and much faster. What will you do with your obsolete P4s, Opterons, and so on? And IBM and others will be putting out early models within a year. Hold onto your hats!

Well, we're not saying that just yet; DDR is the latest bestest RAM memory technology available. We got here by making baby steps in the clock speed of individual memory cells, increasing bus data rates, and using multiples of those rates. But the CPU is still waiting on memory access. It really looks like the current memory technologies will never "catch up" to the feed needs of processors. Two, three, or more layers of caching and the required guessing about what data should be held close to the vest help, but are actually fudges, albeit fairly effective ones.
