    摘要: A memory device capable of performing an overwrite operation, a memory system, and a method of operating the memory system are provided. The method includes receiving one or more write requests, a logical address and data corresponding to the one or more write requests; comparing a result of analyzing at least one of the received one or more write requests, logical address, and data with a threshold value; and writing data using a first update method or a second update method, based on a result of the comparison. When the first update method is selected, the data are written in a region indicated by a physical address corresponding to the logical address according to address mapping information. When the second update method is selected, information of the physical address corresponding to the logical address is changed, and the data are written in a region indicated by the changed physical address.

    摘要: A method of operating a memory system including a nonvolatile memory, having a meta data region and a user data region, and a memory controller having a meta data manager. The method includes programming data to a memory block of the user data region and, by operation of the meta data manager, generating a meta log based on the programming. The meta log is stored to the memory controller. Upon a power-off operation, selectively storing the meta log to the meta data region of the nonvolatile memory based on status information of the nonvolatile memory.
