A memory device with low power consumption is provided. A memory device includes a first logic element generating an output potential by inverting a polarity of a potential of a signal including data in accordance with a first clock signal; second and third logic elements holding the output potential generated by the first logic element; a switching element including a transistor; and a capacitor storing the data by being supplied with the output potential of the first logic element which is held by the second and third logic elements via the switching element. The second logic element generates an output potential by inverting a polarity of an output potential of the third logic element in accordance with a second clock signal different from the first clock signal, and the third logic element generates an output potential by inverting a polarity of the output potential of the second logic element. |
