Abstract:
Apparatuses for controlling defective bit lines in a semiconductor device are described. An example apparatus includes: a first region including a plurality of bit lines, a plurality of word lines and a plurality of memory cells, each memory cell is coupled to an associated bit line and an associated word line; a second region including a plurality of sense amplifiers, each sense amplifier includes a sense node and a column selection switch coupled to the sense node; a third region including a plurality of bleeder circuits, and disposed between the first and second regions; and a plurality of column selection lines. Each bit line from the first region to the second region is coupled to the sense node of an associated one of the plurality of sense amplifiers, and each column selection line from the column selection switch is coupled to an associated bleeder circuit.
