ABSTRACT:
A circuit for controlling an active period of semiconductor memory apparatus includes: an active controller that generates active control signals for determining active periods of two or more individual banks according to whether a refresh operation is performed; and an active signal generator that generates an active signal for each of the banks so as to correspond to the active control signal. According to this structure, it is possible to reduce current consumption to a minimum in a refresh mode, to easily arrange signal lines, and thus to effectively use extra space.
