Flash memory cell with contactless bit line, and process of fabrication

Memory cell array and process of fabrication in which a floating gate is formed on a substrate for each of a plurality of memory cells, a control gate is formed above and in vertical alignment with each of the floating gates, source regions are formed in the substrate between and partially overlapped by first edge portions of the floating gates in adjacent ones of the cells, bit lines are formed in the substrate midway between second edge portions of the floating gates in adjacent ones of the cells, and a select gate is formed across the control gates, the floating gates, the bit lines and the source regions.
