Abstract
A common centroid differential sensing apparatus for sensing the contents of registers in a register array. This differential sensing apparatus includes a first pair of differential bit lines, which traverse across the register array in a predetermined direction (e.g., traverse the length or the width of the array) along a first traversing path or a second traversing path. This differential sensing apparatus also includes a second pair of differential bit lines, which traverse across the register array in the predetermined direction along a third traversing path and a fourth traversing path. Furthermore, the bit lines of one of the pairs of differential bit lines swap every ##EQU1## from the top and the bottom of the register array and swap every ##EQU2## afterwards, while the bit line pairs of the other of the pairs of the differential bit lines swap at ##EQU3## from the top and the bottom of the register array and every ##EQU4## afterwards, where N is an integer greater than 0.
