    Abstract: A nonvolatile memory device includes a memory cell region and a peripheral circuit region. The memory cell region includes a memory block, and the peripheral circuit region includes a control circuit. The memory cell region includes a first metal pad. The peripheral circuit region includes a second metal pad and is vertically connected to the memory cell region by the first metal pad and the second metal pad. The memory block includes a plurality of memory cells disposed in a vertical direction. The control circuit determines whether a data erase characteristic for the memory block is degraded for each predetermined cycle of data erase operation, and performs a data erase operation by changing a level of a voltage applied to selection transistors for selecting the memory block as an erase target block when it is determined that the data erase characteristic is degraded.

    Abstract: A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium. The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when a frame is composed of blocks of a predetermined size includes the steps of: (a) generating blocking information for reducing the blocking effect and ringing information for reducing the ringing noise, from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstructing a bitstream image data for inverse quantization is an intraframe; and (b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. Therefore, the blocking effect and ringing noise can be eliminated from the image restored from the block-based image, thereby enhancing the image restored from compression.
