IBM announces computer memory breakthrough

From Computerworld:

IBM Thursday announced a breakthrough in computer memory technology, which may lead to the development of solid-state chips that can store as much data as NAND flash technology but with 100 times the performance and vastly greater lifespan.

Single atom stores quantum information

From PhysOrg.com:

A data memory can hardly be any smaller: researchers working with Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom. The researchers wrote the quantum state of single photons, i.e. particles of light, into a rubidium atom and read it out again after a certain storage time. This technique can be used in principle to design powerful quantum computers and to network them with each other across large distances.

Data storage takes an electric turn

From PhysOrg.com:

Ferroelectrics could be the way out of a dilemma troubling the chip industry. They provide durable storage and yet can be written and read quickly. Magnetic materials, on the other hand, which are used to produce hard disks and which provide permanent data storage, are sluggish. Semiconductors, for their part, are efficient in handling data, but quick to forget – which means that the electrical charges of their capacitors require constant renewal. Ferroelectrics combine the benefits of both materials. In addition, it may be possible to achieve greater data density in them than previously assumed. They could therefore soon become the material of choice for working memories with a density of several terabits per square inch.
