AN ARRAY OF SPLIT GATE NON-VOLATILE FLOATING GATE MEMORY CELLS HAVING IMPROVED STRAPPING OF THE COUPLING GATES

摘要

An array of non-volatile memory cells with spaced apart first regions extending in a row direction and second regions extending in a column direction, with a channel region defined between each second region and its associated first region. A plurality of spaced apart word line gates each extending in the row direction and positioned over a first portion of a channel region. A plurality of spaced apart floating gates are positioned over second portions of the channel regions. A plurality of spaced apart coupling gates each extending in the row direction and over the floating gates. A plurality of spaced apart metal strapping lines each extending in the row direction and overlying a coupling gate. A plurality of spaced apart erase gates each extending in the row direction and positioned over a first region and adjacent to a floating gate and coupling gate.
