Abstract
A storage device includes a nonvolatile memory device and a storage controller. The storage controller includes a buffer memory, a first volatile memory, a second volatile memory, a processor and a buffer context backup circuit. The buffer memory temporarily stores read data and write data. The first and second volatile memories are included in different power domains. The processor generates buffer allocation information, stores the buffer allocation information in the first volatile memory, and controls an access to the buffer memory based on the buffer allocation information. The buffer context backup circuit performs a context backup operation to back up the buffer allocation information from the first volatile memory to the second volatile memory when entering a power down mode and performs a context restoring operation to restore the buffer allocation information from the second volatile memory to the first volatile memory when exiting from the power down mode.
