Abstract
A memory device that can include a power-supply voltage detector that detects power-supply voltage values and that outputs a detection result indicating which power-supply voltage value is detected; a data-rate setter that sets data rates corresponding to the detection result of the power-supply voltage detector, in synchronization with a rising edge or falling edge of a clock signal; and a memory cell array that performs reading/writing at the data rates set by the data-rate setter.
