From huge memory floppy disks to compact discs to flash drives, the size of computer media formats and memory devices have constantly been shrinking.

Japanese scientists, who had pioneered the miniaturization of floppy disks to CDs, have once again scored a milestone developing a new 3D-stacked memory cell that can revolutionize the concept of memory chips.

As the new machine learning, artificial intelligence (AI) and Big Data are the new buzz words in the tech world, mobile cloud-enabled devices require greater memory that is energy-efficient and smaller in size.

Currently, flash memory devices require relatively large currents to read or write data that will change with the new 3D memory devices.

Making a headway in the direction, a team of researchers of the Institute of Industrial Science at the University of Tokyo have fabricated three-dimensional vertically formed field-effect transistors to produce high-density data storage devices.
