New magnetism-control method could lead to ultrafast, energy-efficient computer memory

A cobalt layer on top of a gadolinium-iron alloy allows for switching memory with a single laser pulse in just 7 picoseconds. The discovery may lead to a computing processor with high-speed, non-volatile memory right on the chip. (credit: Jon Gorchon et al./Applied Physics Letters)

IBM scientists say radical new ‘in-memory’ computing architecture will speed up computers by 200 times

New architecture to enable ultra-dense, low-power, massively-parallel computing systems optimized for AI

The researchers used PCM devices made from a germanium antimony telluride alloy, which is stacked and sandwiched between two electrodes. When the scientists apply a tiny electric current to the material, they heat it, which alters its state from amorphous (with a disordered atomic arrangement) to crystalline (with an ordered atomic configuration). The IBM researchers have used the crystallization dynamics to perform computation in place. (credit: IBM Research)
