Abstract
A semiconductor device comprises a memory cell array, a row control circuit for controlling an access to the memory cell array, and a refresh control circuit for instructing the row control circuit to refresh the memory cell array. After temporarily transiting to a reset state due to an activation of a reset signal, the refresh control circuit instructs to refresh the memory cell array in response to a transition to an initial state due to a de-activation of the reset signal.
