Abstract
An improved memory IC whose memory cells are configured in a chain architecture is disclosed. The first diffusion regions of the cell transistors of the chain are coupled to first capacitor electrodes while the second diffusion regions are coupled to second capacitor electrodes. This ensures that the electric field applied across any of the capacitors of the chain by a plateline pulse is in the same direction. This reduces or avoids asymmetrical hysteresis curves for adjacent memory cells, thereby the improving sensing window.
