    Abstract: A neuron device is described. The neuron device is based on spontaneous polarization switching which includes a plurality of gate electrodes, a plurality of drain electrodes, a plurality of source lines, a dielectric layer, and a semiconductor layer. The gate electrodes are arranged parallel to each other. The drain electrodes are arranged parallel to each other. The source lines are arranged between the gate electrodes and the drain electrodes and parallel to each other. The dielectric layer is formed at intersections between the gate electrodes and the source lines. The semiconductor layer is formed at intersections between the drain electrodes and the source electrodes. The drain electrodes function as synapse-after-neuron linking terminals. The gate electrodes adjust an arrangement direction of electrical dipoles of the dielectric layer to control a firing time point and a firing height of the neuron device.

    Abstract: An electronic device includes: a storage device including multiple segments configured to store data; a buffer memory configured to store segment attributes corresponding to the multiple segments, respectively; and one processor electrically connected to the storage device and the buffer memory. The one processor is configured to: determine, based on two or more parameters related to a data requested to be written, a data attribute; store the data requested to be written in a segment of the multiple segments, the segment being corresponding to the data attribute among the multiple segments; store a segment attribute of the segment, which is determined based on the data attribute in the buffer memory; update the data attribute, based on a data modification time of the data requested to be written; and update the segment attribute, based on the updated data attribute.

    Abstract: An electronic device in an example embodiment may include a communication interface configured to receive an original file, a memory, and a processor. The processor may generate bit information corresponding to uppercase and lowercase letters included in a filename of the original file. The processor may generate a case insensitive (CI) filename in which the filename of the original file is expressed by characters of a first type. The processor may encrypt the CI filename and may calculate a first hash value corresponding to the encrypted CI filename. The processor may record filename metadata including at least one of the encrypted CI filename, a length of the encrypted CI filename, the first hash value, and the bit information, in the memory. The processor may search for a target file to be found based on the filename metadata.
