Abstract
A memory system includes a nonvolatile memory device; a random access memory configured to store, in response to an unmap request received from a host device, a flag information indicating that an unmap address as a target of the unmap request is unmapped; and a control unit configured to flush the flag information to the nonvolatile memory device, wherein the control unit flushes the flag information to the nonvolatile memory device when a first condition is satisfied.
