Memory Architectures Undergo Changes

By Ed Sperling Memory architectures are taking some new twists. Fueled by multi-core and multiple processors, as well as some speed bumps using existing technology, SoC makers are beginning to rethink how to architect, model and assemble memory to improve speed, lower power and reduce cost. What’s unusual about all of this is that it doesn’t rely on new technology, although there certai... » read more

Semiconductor Memory Aids

By Brian Fuller It's not hard to forget that semiconductor memory remains one of the most relentless challenges in system design. It sometimes doesn’t get the ink that sexier semiconductor design topics do, but it’s there. Always. Twenty years ago this year, University of Virginia computer scientists William Wulf and Sally McKee published a paper that popularized the term semiconductor ... » read more
