A suspected member of the Al Qaeda terrorist group, arrested in May last year in Germany, was found with a memory stick hidden in his underwear. Police discovered the stick contained a password-protected folder with pornographic ...
(PhysOrg.com) -- Lyric Semiconductor has unveiled a new type of chip that uses probability inputs and outputs instead of the conventional 1's and 0's used in logic chips today. Crunching probabilities is much more applicable ...
A class of nonvolatile memory devices, called MRAM, based on quantum magnetic materials, can offer a thousandfold performance beyond current state-of-the-art memory devices. The materials known as antiferromagnets were previously ...
