    • Provided are a divided clock generating device and a divided clock generating method. The divided clock generating device includes a chip selection flip flop which generates a chip selection signal synchronized with an internal clock signal, a clock dividing unit which generates a plurality of second divided even/odd clock signals using a first divided clock signal and outputs the internal clock signal, and a clock comparator which selects one of the second divided even/odd clock signals by using the chip selection signal which is synchronized with the internal clock signal. The clock dividing unit divides the internal clock signal by using the first divided clock signal and one selected among the second divided even/odd clock signals according to the selection result of the clock comparator.
