Abstract
The memory array circuit this invention provides connection of segmented bitlines to bitline decoding circuitry while, at the same time, providing connection of combined wordlines wordline decoding circuitry. The segmentation and decoding connections permit faster speed of operation with minimal or no area penalty. The area penalty is avoided by driving common wordlines in each of the segments, effectively increasing the wordline pitch at the wordline decoder, while at the same time decreasing the number of wordline decodes required. The segmentation also permits location of the decoder circuit away from the signal and routing decode outputs.
