Abstract
This disclosure relates to memory array organization of single transistor cells and the differential sense amplifiers provided therewith. To accommodate the differential sense amplifiers, the array is laid out in rows and functional columns where a functional column consists of a pair of columns such that odd row cells are connected to the odd column of the pair and even row cells are connected to the even column of the pair. A differential sense amplifier is then provided for each pair of odd and even columns which are inherently balanced at the sense amplifier terminals. Single ended or edge ended I/O circuitry is provided with direct access to the respective pairs of columns.
