Abstract
According to one aspect of the present invention, an apparatus is provided that includes a first global bit line, a second global bit line, a first block, a second block, and a reference cell array. The first block contains a first local bit line and a plurality of memory cells coupled to the first local bit line. The first local bit line can be selectively coupled to the first global bit line based upon a first control input. The second block contains a second local bit line and a plurality of memory cells coupled to the second local bit line. The second local bit line can be selectively coupled to the second global bit line based upon a second control input. The reference cell array contains a plurality of reference cells. The plurality of reference cells can be selectively coupled to either the first global bit line or the second global bit line based upon a third control input.
