Patent ID: 8760904

Claim:
An One-Time Programmable (OTP) memory, comprising: a plurality of OTP cells, each including an OTP element and a diode as program selector having at least a first active region with a first type of dopant to provide a first terminal of the diode, and a second active region with a second type of dopant to provide a second terminal of the diode, both active regions being fabricated from sources or drains of CMOS devices and residing in a common CMOS well, the first terminal of the diode coupled to a first terminal of the OTP element, the OTP element being programmable by conducting a current flowing through the OTP element and the diode; a plurality of local wordlines, each coupled to a plurality of the OTP cells via the second terminal of the diodes and having a first resistivity; a plurality of global wordlines, each coupled to at least one of the local wordlines and having a second resistivity; and a plurality of bitlines, each coupled to a plurality of the OTP cells via the second terminal of the OTP element.
