  • Publication number: 20250280535
    Abstract: A single-poly non-volatile memory cell is provided. In the memory cell, a polysilicon gate layer of a gate structure is used as a floating gate of the floating gate transistor. During an ion implantation process, a relatively small amount of dopant is implanted into the polysilicon gate layer. Consequently, the dopant concentration of the polysilicon gate layer is less than the dopant concentration of a merged n-type doped region beside the gate structure. Since the defects in the polysilicon gate layer are reduced, the data retention capability of the memory cell is effectively enhanced.

    Abstract: An erasable programmable single-poly non-volatile memory cell and an associated array structure are provided. In the memory cell of the array structure, the assist gate region is composed at least two plate capacitors.
