Phys.org August 9, 2018 Intel’s newest solid-state drive, the Intel SSD DC P4500, is about the size of a 12-inch ruler and can store 32 terabytes. It is built on Intel 3-D NAND technology, which stacks memory cells atop each other in multiple extremely thin layers, instead of just one. Memory cells in the P4500 are stacked 64 layers deep. In data centers, the no-moving-parts ruler-shaped SSDs can be lined up 32 side-by-side, to hold up to a petabyte in a single server slot. Compared with a traditional SSD, the “ruler” requires half the airflow to keep cool. And compared […]

Manipulating single atoms with an electron beam
Eurekalert July 9, 2018 An international team of researchers (Austria, Norway, Belgium) used the advanced electron microscope to move single silicon atoms in graphene with atomic precision. They have taken the first steps towards automation by detecting the jumps in real time. The new results also improve theoretical models of the process by including simulations. In total, the researchers recorded nearly 300 controlled jumps. Silicon impurity could be moved back and forth between two neighboring lattice sites separated by one tenth-billionth of a meter, like flipping an atomic-sized switch. In principle, this could be used to store one bit of […]
A step closer to single-atom data storage
Phys.org July 10, 2018 Researchers in France found that the holmium atoms could retain record-breaking coercivity in a magnetic field exceeding 8 Tesla. Only at around 45K, the magnets began to spontaneously align themselves to the applied magnetic field. This showed that they can withstand relatively high temperature perturbations and might point to the way forward for running single-atom magnets at more commercially viable temperatures. Each atom can store a single bit of data that can be written and read using quantum mechanics. Such devices promise enormous data capacities… read more. Open Access TECHNICAL ARTICLE
