Abstract
An improved cell array and sense amplifier structure and embodied method are disclosed. The structure exhibits an improved noise characteristic by decreasing a coupling noise which occurs between bit lines by using, as a reference bit line, a bit line from an array of memory cells other than the array to which the bit line belongs, thus forming a predetermined spacing between a bit line and a reference bit line. The structure includes: an upper sense amplifier having an input terminal commonly connected with a first pair of bit lines of an adjacent first cell array and another input terminal commonly connected with a first pair of bit lines of a non-adjacent second cell array; and a lower sense amplifier having an input terminal commonly connected with a second pair of bit lines of the second cell array and another input terminal connected with a second pair of bit lines of the first cell array.
