Abstract
A memory module includes an emergency power supply block, a volatile memory, a nonvolatile memory, and a control block configured to control data of the volatile memory to be backed up in the nonvolatile memory, by using a power supplied from the emergency power supply block, upon a power failure, and control the data of the volatile memory to be recovered, by using data backed up in the nonvolatile memory, upon a power recovery, wherein the control block controls the data of the volatile memory not to be backed up while controlling the data of the volatile memory to be recovered, even upon the power failure.
