Patent ID: 7102938

Claim:
An internal voltage generation control circuit comprising: a first latch for receiving, as an input signal, a column active pulse signal that is generated after a read or write command is input, and latching state information of the column active pulse signal, which is received when a clock signal is enabled, during a predetermined time, and then outputting the latched state information; second to n-th latches, wherein a k-th latch receives, as an input signal, an output signal of a k−1-th latch, and latches state information of the output signal of the k−1-th latch, which is received when the clock signal is enabled, during a predetermined time, and then outputs the latched state information, where k and n are natural numbers satisfying 2≦k≦n; and a logic unit for performing a logical operation between the column active pulse signal and output signals of the first to n-th latches and outputting an internal voltage generation control signal.
