Abstract
In an embodiment a memory cell includes a first doped well of a first conductivity type embedded in a second doped well of a second conductivity type, the second conductivity type being opposite to the first conductivity type, a third doped well of the second conductivity type embedded in a fourth doped well of the first conductivity type, a first wall in contact with the second and fourth doped wells, the first wall including a conductive or semiconductor core and an insulating liner, the insulating liner extending between the conductive or semiconductor core and the second and fourth doped wells, and a stack of layers comprising a first insulating layer, a first semiconductor layer, a second insulating layer and a second semiconductor layer, the first insulating layer being in contact with the second and fourth doped wells.
