Abstract:
A semiconductor device with multiple strap-contact configurations for a memory cell array. An array with memory cells interconnected with bit-lines, control-gate lines, erase gate lines, common-source lines, and word-lines is provided. In one aspect of an illustrative embodiment, a strap-contact corridor is spaced at n bit-line intervals (n>1) across the array. The strap-contact corridor comprises strap-contact cells, which provide electrical interconnection between control-gate lines, erase gate lines, common-source lines, and word-lines and their respective straps.
