    Abstract: The present invention relates to a floating-gate MOS transistor, comprising drain and source regions implanted into a silicon substrate, a channel extending between the drain and source regions, a tunnel oxide, a floating gate, a gate oxide and a control gate extending according to a determined gate length. According to the present invention, the control gate comprises a small gate and a large gate arranged side by side and separated by an electrically insulating material. Application to the production of memory cells without access transistor, and to the implementation of an erase-program method with reduced electrical stress for the tunnel oxide.
