    Abstract: A method is provided to operate a storage device including a storage controller and a plurality of nonvolatile memory devices. A plurality of original data blocks are received at the storage controller from a host. An original parity block is generated based on the original data blocks. The original data blocks and the original parity block are stored in respective ones of the nonvolatile memory devices, wherein a first original data block of the original data blocks is stored in a first one of the nonvolatile memory devices, and wherein the original parity block is stored in a second one of the nonvolatile memory devices. A new data block corresponding to the first original data block is received at the storage controller from the host after storing the original data blocks and the original parity block. The new data block is stored in the first nonvolatile memory device. A new parity block is generated at the second nonvolatile memory device based on the original parity block and based on differences between the first original data block and the new data block.

    Abstract: A memory device, a memory system, and/or a method of operating a memory system includes measuring, using processing circuitry, an erase program interval (EPI) of a memory group included in a non-volatile memory (NVM), the EPI being a time period from an erase time point to a program time point of the memory group, determining, using the processing circuitry, a plurality of program modes based on a number of data bits stored in each memory cell of the memory group, selecting, using the processing circuitry, a program mode for the memory group from the plurality of program modes, based on the measured EPI of the memory group, and performing, using the processing circuitry, a program operation on the memory group corresponding to the selected program mode.

    Abstract: A nonvolatile memory device includes a first semiconductor layer and a second semiconductor layer. The first semiconductor layer includes word-lines, at least one string selection line, at least one ground selection line, and a memory cell array including at least one memory block. The second semiconductor includes a first address decoder and a second address decoder. The first address decoder is disposed under a first extension region adjacent to a first side of a cell region and includes a plurality of first pass transistors driving the word-lines, the at least one string selection line, and the at least one ground selection line. The second address decoder is disposed under a second extension region adjacent to a second side of the cell region and includes a plurality of second pass transistors driving the at least one string selection line and the at least one ground selection line.
