Abstract: A memory device includes a memory cell array, a control logic which controls a read operation to read hard decision data and soft decision data from each page, and a page buffer which includes a first latch related to sensing of the hard decision data and a second latch related to sensing of the soft decision data. The control logic controls performing a first sensing operation of storing a value determined based on a first offset level, in the second latch, at a first sensing timing, and a second sensing operation of storing a value determined based on a second offset level, in the second latch, at a second sensing timing, and performs a control operation to provide a set signal SET to the second latch in the first sensing operation, and provide a reset signal RST to the second latch in the second sensing operation.

Abstract: A nonvolatile memory device includes a plurality of memory blocks and a control logic circuit configured to perform a first page on-chip valley search (OVS) operation on memory cells connected to one wordline of a memory block selected in response to an address, among the plurality of memory blocks, in response to a first read command. The control logic circuit is further configured to change a read level of at least one state using detection information of the first page OVS operation, and to perform a second page read operation on the memory cells using the changed read level in response to a second read command.

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 method and an apparatus are provided for executing applications. Based on receiving a first user input, a first window comprising number keys is displayed. Based on a second user input selecting one of the number keys, the first window and a second window are displayed together. The second window includes a list of applications, each represented by an icon image and an application name. Based on an application being selected from a list of applications, the selected application is mapped to the selected number key and an icon image corresponding to the selected application is included in the selected number key. After the selected application is mapped, a third user input is received corresponding to the selected number key. In response to receiving the third user input, a first function is performed associated with the selected application based on a duration of the third user input.
