ABSTRACT:
An internal voltage generation control circuit and an internal voltage generation circuit using the same are provided. The internal voltage generation control circuit comprises first to n-th latches and a logic unit. The first latch receives, as an input signal, a column active pulse signal generated after a read/write command is input, and latches state information of the column active pulse signal, received when a clock signal is enabled, during a predetermined time, and then outputs the latched information. A k-th latch (2≦k≦n) receives an output signal of a k-1-th latch, and latches state information of the output signal of the k-1-th latch, received when the clock signal is enabled, during a predetermined time, and then outputs the latched information. The logic unit performs a logical operation between the column active pulse signal and output signals of the n latches and outputs an internal voltage generation control signal.
