Abstract
A current comparator may include a current comparison block configured to compare current flowing through first and second input terminals; a first current control unit configured to control current flowing through the first input terminal in response to a voltage of a first node; a second current control unit configured to control current flowing through the second input terminal in response to a voltage of a second node; a first driving unit configured to drive the first node with a first voltage higher than a read voltage in a non-comparison period, and drive the first node with the read voltage in a comparison period; and a second driving unit configured to drive the second node with a second voltage higher than a reference voltage in the non-comparison period, and drive the second node with the reference voltage in the comparison period.
