A solid state drive (SSD) device includes nonvolatile memory devices, a controller, a main power supply circuit and an auxiliary reprogram device. The controller controls the nonvolatile memory devices. The main power supply circuit provides an operation voltage to the nonvolatile memory devices and the controller using a supply voltage provided through a power line. The auxiliary reprogram device provides an auxiliary supply voltage to the nonvolatile memory devices and the controller and generates a reprogram command. The controller is configured to, if the SSD is not powered, perform periodically at a first period a reprogram operation on the nonvolatile memory devices.
