    摘要: A memory managing method is provided for a memory system, including a nonvolatile memory device and a memory controller controlling the nonvolatile memory device. The memory managing method includes determining whether a program-erase number of a memory block in the nonvolatile memory device reaches a first reference value; managing a life of the memory block according to a first memory managing method when the program-erase number of the memory block is determined to be less than the first reference value; and managing the life of the memory block according to a second memory managing method different from the first memory managing method when the program-erase number of the memory block is determined to be greater than the first reference value.

    摘要: The operating method of a data storage device includes storing data in a buffer memory according to an external request, and determining whether the data stored in the buffer memory is data accompanying a buffer program operation of a memory cell array. When the data stored in the buffer memory is data accompanying the buffer program operation, the method further includes determining whether a main program operation on the memory cell array is required, and when a main program operation on the memory cell array is required, determining a program pattern of the main program operation on the memory cell array. The method further includes issuing a set of commands for the main program operation on the memory cell array to a multi-bit memory device based on the determined program pattern.

    摘要: A data storage device includes a multi-bit memory device including a memory cell array, the memory cell array including a first memory region and a second memory region, and a memory controller including a buffer memory and configured to control the multi-bit memory device. The memory controller is configured to control the multi-bit memory device to execute a buffer program operation in which data stored in the buffer memory is stored in the first memory region, and to control the multi-bit memory device to execute a main program operation in which the data stored in the first memory region is stored in the second memory region. The memory controller is further configured to generate parity data based upon the data stored to the first region, the parity data being copied from the first memory region to the second memory region via the main program operation.

    摘要: A nonvolatile memory includes a plurality of N-bit multi-level cell (MLC) memory cells and a controller. The plurality of N-bit MLC memory cells are for storing N pages of data, each of the MLC memory cells programmable into any one of 2N threshold voltage distributions, where N is a positive number. The controller is configured to program the N pages of data into the MLC memory cells, and to execute a partial interleave process in which the N pages of data are divided into M page groups, where M is a positive number and where each page group includes at least one of the N pages of data, and in which each of the M page groups is applied to an error correction code (ECC) circuit to generate parity bits for the respective M page groups, where a bit-error rate (BER) among the pages within each of the M groups is equalized by the partial interleave process
