Abstract
A semiconductor memory is comprised of a semiconductor substrate having first and second spaced apart arrays of memory cells disposed thereon. A plurality of first pairs of bit lines couple to the cells of the first array, and a corresponding plurality of second pairs of bit lines couple to the cells of the second array. Disposed between each first pair and corresponding second pair of bit lines is one X sense amplifier. This amplifier includes a set node selectively coupled to one bit line of the first pair and to one bit line of the second pair, and a reset node selectively coupled to the opposite bit lines of the first and second pair for selectively sensing charge on the four bit lines.
