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 memory system comprises a nonvolatile memory device comprising a memory cell array comprising first and second memory blocks, and a memory controller configured to control the nonvolatile memory device to read data from the first memory block, selectively determine an error correction operation to be performed on the data after it is read from the first memory block based on a state of at least one of the first and second memory blocks, and then store the data in the second memory block.
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:
A method of operating a memory device includes: determining an erase mode based on a number of erase cycles performed on a memory block and an erase voltage utilized to perform each erase cycle; and setting an erase voltage level for executing an erase operation on the memory block based on the determined erase mode.
