Abstract: A storage device includes a nonvolatile memory device and a memory controller to control the nonvolatile memory device. The nonvolatile memory device includes a memory cell array. The memory cell array includes a normal cell region, a parity cell region and a redundancy cell region. First bit-lines are connected to the normal cell region and the parity cell region and second bit-lines are connected to the redundancy cell region. The memory controller includes an error correction code (ECC) engine to generate parity data. The memory controller stores user data in the normal cell region, controls the nonvolatile memory device to perform a column repair on first defective bit-lines among the first bit-lines, assigns additional column addresses to the first defective bit-lines and the second bit-lines and stores at least a portion of the parity data in a region corresponding to the additionally assigned column addresses.

Abstract: A nonvolatile memory device that performs two-way channel precharge during programming is provided. A program operation of the nonvolatile memory device simultaneously performs a first precharge operation in a bit line direction and a second precharge operation in a source line direction on channels of a plurality of cell strings before programming a selected memory cell to initialize the channels. The first precharge operation precharges the channels of the plurality of cell strings using a first precharge voltage applied to the bit line through first and second string selection transistors, and the second precharge operation precharges the channels of the plurality of cell strings using a second precharge voltage applied to the source line through first and second ground selection transistors.
