  • Dual thin oxide ESD network for nonvolatile memory applications
    Patent number: 5872378
    Abstract: An Electric Static Discharge (ESD) protection network for nonvolatile memory using a high voltage dual thin oxide MOSFET. In one aspect, there is a dual oxide electric static discharge (ESD) protective network for nonvolatile memory in which ESD protection is provided using a thick oxide PFET in a thick epitaxial layer with sequence independent circuitry. The dual oxide ESD network includes a high voltage PFET ESD network for 12 V to 5 V applications as well as a low voltage PFET network 5 V to 3 V applications taking advantage of dual oxides supported by the disclosed technology. The circuit saves space, is migratable, improves reliability, and it is voltage differential independent.
