University of California, Riverside (UCR) researchers say they have developed a type of holographic memory device that could provide unprecedented data storage capacity and data-processing capabilities in electronic devices.

The memory device uses spin waves instead of optical beams because spin-wave devices are compatible with conventional electronic devices and can operate at a much shorter wavelength than optical devices, allowing for smaller electronic devices that have greater storage capacity.

The researchers found it feasible to apply holographic techniques developed in optics to magnetic structures to create a magnonic holographic memory device. "The results open a new field of research, which may have tremendous impact on the development of new logic and memory devices," says UCR professor Alexander Khitun. He says the key breakthrough came when the researchers realized the device could complement circuits, or help them accomplish certain tasks, such as image recognition, speech recognition, and data processing.
