Resumen de Shrinking Memory.
The article reports on research for ferroelectric random-access memory. Ferroelectric random-access memory, or FRAM, relies on lining up dipoles (separated charges) to represent 0 and 1, giving it the speed of RAM and, notably, the ability to retain data without power. Unfortunately, FRAM does not offer as much storage space: dipoles in small ferroelectric bits do not all line up easily. Now University of Arkansas researchers may have discovered a way to shrink ferroelectric bits. Such vortices mark a new phase in ferroelectric materials, and because they are tiny and interact weakly with one another, they can be packed very closely together, which could increase their memory density 100,000 times.
