    Abstract: A nonvolatile memory device includes a first semiconductor layer including an upper substrate in which word-lines extending in a first direction and bit-lines extending in a second direction are disposed and a memory cell array, a second semiconductor layer, a control circuit, and a pad region. The memory cell array includes a vertical structure on the upper substrate, and the vertical structure includes memory blocks. The second semiconductor layer includes a lower substrate that includes address decoders and page buffer circuits. The vertical structure includes via areas in which one or more through-hole vias are provided, and the via areas are spaced apart in the second direction. The memory cell array includes mats corresponding to different bit-lines of the bit-lines. At least two of the mats include a different number of the via areas according to a distance from the pad region in the first direction.

    Abstract: A storage device includes a first memory device including a plurality of memory blocks, and a plurality of pages included in each of the plurality of memory blocks, a second memory device configured to store first degradation information of the first memory device, and a controller configured to perform a first read operation on the first memory device using a first read voltage, to acquire the first degradation information, and to perform a second read operation on the first memory device using a second read voltage. The second read voltage is calculated using second degradation information of the first memory device estimated using the first degradation information. Each of the first degradation information and the second degradation information includes the number of error bits of each of the plurality of pages.
