Abstract

Embodiments of a simple and cost-free multi-time programmable (MTP) structure for non-volatile memory cells are presented. The memory cell includes a substrate. A floating gate is disposed over a transistor well. A control gate disposed over a control well is coupled to the floating gate. The control gate includes a control capacitor. A non-self-aligned source/drain (S/D) region is disposed within the transistor well and serves as an erase terminal.
