ABSTRACT:
The invention provides a sense amplifier apparatus (100) for bit line signals (103, 104) having a bit line pair which comprises two bit lines (107, 108) to which complementary bit line signals (103, 104) are applied, and a switching device (101) which is connected cross-coupled between the bit line, with a first transistor pair (201, 202) and a second transistor pair (105, 106), with the switching device having a switching transistor pair which comprises two transistors (205; 206) connected in series with the first transistors (201; 202), in which a switching signal (207) can be applied to the gates of the switching transistors (205; 206) and, furthermore, a holding device (102) being connected between the bit lines (107, 108) and maintaining the levels, which are switched by the switching device (101), on the bit line signals (103, 104) which are applied to the bit lines (107, 108).
