    摘要: An erase method of a nonvolatile memory device is provided which includes receiving an erase request; selecting an erase mode of a memory block corresponding to the erase request, based on an access condition of the nonvolatile memory device managed by a memory controller; and controlling the nonvolatile memory device to erase the memory block according to the selected erase mode. The erase mode includes a fast erase mode of which an erase time for the memory block is shorter than a reference time and a slow erase mode of which an erase time for the memory block is longer than the reference time.

    摘要: Disclosed is a method of operating a nonvolatile memory device which includes a first memory area and a second memory area, the number of pages being stored in each word line of the first memory area being smaller than the number of pages being stored in each word line of the second memory area, and the first memory area being configured to buffer data to be written in the second memory area. The method includes sensing pages stored in the first memory area to store the sensed pages in a page buffer; receiving an address for storing pages stored in the page buffer in the second memory area; and randomizing the pages stored in the page buffer based on the address.

    摘要: A nonvolatile memory device comprises a cell array connected to a plurality of bit lines in an all bit line structure, a page buffer circuit connected to the plurality of bit lines, and control logic configured to control the page buffer circuit. The control logic controls the page buffer circuit to sense memory cells corresponding to both even-numbered and odd-numbered columns of a selected page in a first read mode and to sense memory cells corresponding to one of the even-numbered and odd-numbered columns of the selected page in a second read mode. A sensing operation is performed at least twice in the first read mode and once in the second read mode.

    摘要: An address mapping table includes arrays each being allocated to a logical address and in which a physical address mapping the logical address is stored. In the case where the physical address mapped to the logical address is changed, a value of a difference between a pre-changed physical address and a physical address to be changed is stored in the address mapping table. When the logical address is mapped to the physical address, the mapped physical address is calculated by adding up the logical address and values stored in the arrays allocated to the logical address. The address mapping table is managed to decrease the number of erase counts of a memory device in which the address mapping table is stored.
