    Abstract: The present invention relates to metal oxide based memory devices and methods for manufacturing such devices; and more particularly to memory devices having data storage materials based on metal oxide compounds fabricated with a roughness tuning process including an ion bombardment step of a bottom electrode surface prior to formation of a memory element on the bottom electrode surface. Ion bombardment improves the flatness of the bottom electrode which is beneficial in achieving a more uniform electrical field during operation, which improves device reliability.

    Abstract: Disclosed is a memory device including plural bit lines, plural word lines and a control circuit. The bit lines are configured to receive pixel data of an image. Each word line includes plural factor units. The factor units of each word line are configured differently according to plural factors of a filter. When processing a first area of the image by the filter, the control circuit inputs the pixel data within the first area of the image to the bit lines, and enables one of the word lines for operation. When processing a second area of the image by the filter, the control circuit maintains the pixel data within the second area overlapping the first area on the bit lines, and inputs the pixel data within the second area which doesn't overlap the first area to the bit lines, and enables another one of the word lines for operation.
