ELECTRONIC DEVICE INCLUDING A NONVOLATILE MEMORY STRUCTURE HAVING AN ANTIFUSE COMPONENT |
摘要 |
An electronic device can include a nonvolatile memory cell, wherein the nonvolatile memory cell can include a substrate, an access transistor, a read transistor, and an antifuse component. Each of the access and read transistors can include source/drain regions at least partly within the substrate, a gate dielectric layer overlying the substrate, and a gate electrode overlying the gate dielectric layer. An antifuse component can include a first electrode lying at least partly within the substrate, an antifuse dielectric layer overlying the substrate, and a second electrode overlying the antifuse dielectric layer. The second electrode of the antifuse component can be coupled to one of the source/drain regions of the access transistor and to the gate electrode of the read transistor. In an embodiment, the antifuse component can be in the form of a transistor structure. The electronic device can be formed using a single polysilicon process. |
