摘要：
In an embodiment of the invention, a non-volatile anti-fuse memory cell is disclosed. The memory cell consists of a programmable n-channel diode-connectable transistor. The poly-silicon gate of the transistor has two portions. One portion is doped more highly than a second portion. The transistor also has a source with two portions where one portion of the source is doped more highly than a second portion. The portion of the gate that is physically closer to the source is more lightly doped than the other portion of the poly-silicon gate. The portion of the source that is physically closer to the lightly doped portion of the poly-silicone gate is lightly doped with respect to the other portion of the source. When the transistor is programmed, a rupture in the insulator will most likely occur in the portion of the poly-silicone gate that is heavily doped.
