US Patent 7885126 Apparatus for controlling activation of semiconductor integrated circuit

An apparatus for controlling an activation of semiconductor integrated circuit includes: an active control unit configured to generate active control signal for determining activation of banks; and a plurality of active signal generating units configured to input the active control signal commonly, and generate active signals for activating the banks to according 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.
