Abstract
The substrate current generated during the operation of a bit line equalizer can be reduced by adapting PMOS transistors which have a smaller ionization coefficient in its carrier of a hole than NMOS transistors for maintaining a pair of bit lines at the same potential before a sense amplifier is operated. Thus, the substrate voltage can be stabilized by reducing the substrate current in the operation of the bit line equalizer.
