Abstract: In a data storage control device for writing data into a first memory that is non-volatile memory, an information receipt unit receives voltage-related information from a power source control device. A condition determination unit determines whether a voltage condition is satisfied. When the condition determination unit determines that the voltage condition is satisfied during execution of a writing process, a memory controller determines whether a predetermined storage condition is satisfied. When the storage condition is not satisfied, the memory controller executes a first response process of withdrawing writing residual data into the first memory but setting a validity flag as invalid. When the storage condition is satisfied, the memory controller executes a second response process of writing the residual data into the first memory.
