    摘要: Methods of operating integrated circuit devices include updating a mapping table with physical address information by reading forward link information from a plurality of spare sectors in a corresponding plurality of pages within a nonvolatile memory device and then writing mapping table information derived from the forward link information into the mapping table. This forward link information may be configured as absolute address information (e.g., next physical address) and/or relative address information (e.g., change in physical address). This updating of the mapping table may include updating a mapping table within a volatile memory, in response to a resumption of power within the integrated circuit device. This resumption of power may follow a power failure during which the contents of the volatile memory are lost.
