ABSTRACT:
A sensing circuit, in which a semidirect system is used for simplifying a circuit system, is disclosed. The sensing circuit includes: a data bus having a data line and a data bar line for reading operations and/or writing operations; a first transistor for controlling an indirect read operation; a second and third transistor, connected to the data lines, respectively, each also being connected to the same end of said first transistor, for selectively connecting one of the data lines to the first transistor; and a fourth transistor and a fifth transistor for selectively connecting the data bus to the bit line and the bit bar line, respectively, to control a direct writing operation.
