ABSTRACT:
A low power sense amplifier for semiconductor memory devices includes: a sense-amplifying part that senses and amplifies first and second input signals from first and second input terminals, and produces first and second output signals having different voltage levels from each other via the first and second output terminals; a charging part for charging the first and second output terminals of the sense-amplifying part prior to the sensing and amplifying operation of the sense-amplifying part; a control part for producing a control signal for disabling the sense amplifying part if the sense-amplifying part produces output signals having different voltage levels from each other.
