MRAM Moves to Higher Densities

Everspin introduced a 16-megabit MRAM product today focused on all applications requiring both SRAM performance and nonvolatile data storage. This latest product also addresses MRAM’s traditional high reliability and high-performance market segment, while advancing the technology to a higher density. The new MR4A16B is a 3.3-volt parallel I/O non-volatile memory product featuring... More

HP’s Memristor

PWe have been discussing forecasts of technology advances, and here is another critical forecast to add to the list. HP Labs has updated the status of its memristor technology in a paper published by HP’s Information and Quantum Systems Lab this week in the journal " Nature ". Nearly all of the discussion about memristors so far has focused on their use for data storage; HP predicts... More

Changing Market Conditions

In reponse to my recent post, First Quarter Evaluation , a reader commented on the status of a phase change program in 2004, and I thought that the response might have some general interest. I suspect that any reader who has been following these technologies for that long might also recall the presentation by two very large and well-known companies at the VLSI symposium in Kyoto in 2003...

First Quarter Evaluation

Forecasts and commitments serve the purpose of providing measurements, and my 2010 predictions are not starting off very well. My predictions for the first half of the year were that Numonyx would have phase-change memory samples available in the first quarter, that Samsung would respond with a new round of phase-change memory samples in the second quarter, and that Adesto would have samples...

The Impact of Lithography Challenges – Part 2

After first apologizing to Dr. Tredennick if I have somewhat mangled the points of his presentation—I completely agree with Dr. Tredennick assessment of the manufacturing challenges ahead.    I also believe that this manufacturing issue has a double-barreled impact on the production costs of memory technologies.  The first impact is relative to the ability to...
