Micron to tap IBM chip-stacking tech for fast memory

IBM and Micron Technology are beginning to produce a new memory chip based on technology designed to boost memory speeds 15-fold.

The technology, the companies announced today, will be used to make a Hybrid Memory Cube chip that will be commercially manufactured by Micron, the largest manufacturer of memory chips in the United States and one of the largest in the world. IBM plans to manufacture and supply the "controller" silicon that will be used in the memory as well as in the 3D-chip technology.

The joint efforts are designed to result in memory chips that realize the … Read more

Sun shows off its proximity communication silicon

Proximity communication--an interconnect technology being devised by Sun Microsystems that lets two devices swap data just by being near each other--isn't ready for commercial release, but the company is showing off samples.

At the Gartner Symposium/ITxpo in Las Vegas this week, David Douglas of Sun Labs showed off silicon that embodies the concept. Here is a link to a video on his talk on ZDNet. Douglas is holding the chips, which he didn't demonstrate in action.

In proximity communication, two capacitors sit near each other. When data is sent to capacitor one, it gets charged. The charge … Read more
