Abstract

For perfect states of balance on sense nodes, there is provided a sense amplifier circuit comprising a balancing circuit capable of establishing an electrical path between not only the sense nodes but also the sense nodes and control nodes which are operable to control transistors provided between the sense nodes and a voltage supply to apply the supply voltage level to one of the sense nodes and remain low level on the other sense node for preparation of reading out of an accessed information. The current path simultaneously established on the beginning of precharging prevents the sense nodes from influence of the large differential voltage on the control nodes, thereby producing the perfect balance states on all the nodes and being conducive to precise judgement on the read out information.
