Abstract
A memory system includes a nonvolatile semiconductor memory, a controller that controls the nonvolatile semiconductor memory, and a temperature sensor that acquires an operating temperature of at least one of the nonvolatile semiconductor memory and the controller. The controller calculates a temperature parameter based on operating temperatures acquired by the temperature sensor over a period of time, and switches between a plurality of operation settings in which electric power consumptions of the memory system vary, based on the temperature parameter.
