    摘要: A resistive memory system having a plurality of memory cells includes a memory device having a resistive memory cell array and a controller. The controller generates write data to be written to the memory cell array by encoding input data such that the input data corresponds to an erase state and a plurality of programming states that a memory cell may have. The input data is encoded such that at least one of the number of memory cells assigned a first programming state and the number of memory cells assigned a second programming state is smaller than at least one of the numbers of memory cells in the erase state and the other programming states. The first programming state has a highest resistance level among the plurality of programming states, and the second programming state has a second highest resistance level among the plurality of programming states.

    摘要: An erase method of a nonvolatile memory device includes setting an erase mode, and performing one of a normal erase operation and a quick erase operation according to the set erase mode. The normal erase operation is performed to set a threshold voltage of a memory cell to an erase state which is lower than a first erase verification level. The quick erase operation is performed to set a threshold voltage of a memory cell to a pseudo erase state which is lower than a second erase verification level. The second erase verification level is higher than the first erase verification level.

    摘要: A nonvolatile memory (NVM) device includes a plurality of memory blocks and a control logic receiving a specific command and an address. The control logic may perform a cell count-based dynamic read (CDR) operation on memory cells connected to one of wordlines of a selected block, among the plurality of memory blocks, in response to the address. The control logic includes a cell count comparator circuit configured to compare: (1) a first cell count value for a highest state among a plurality of states with at least one reference value according to the CDR operation and (2) a second cell count value for an erase state among the plurality of states with the at least one reference value. Additionally, the control logic includes a read level selector configured to select a read level according to a result of the comparison of the cell count comparator circuit.
