Anti-Fuse

Purpose

The Anti-Fuse is a secure One-Time Programmable (OTP) memory with redundant architecture and margin check mechanism.

Features

▪ 32-bit OTP anti-fuse memory (size customized on request);
▪ redundant architecture preventing from reading errors;
▪ margin check mode evaluating the anti-fuse state reliability;
▪ high-voltage manager controlling the external blowing voltage;
▪ two operating modes:
− secure mode protecting against bit-flip attacks;
− low-power mode reducing significantly the current consumption.
▪ operating junction temperature range: -40°C to 125°C;
▪ electrical characteristics of a 65 nm CMOS implementation:
− power supply voltage range: 1.2 V ±10%;
− typical operating current lower than 100 µA;
− low-power mode operating current smaller than 1 µA;
− wake-up time shorter than 500 µs;
− silicon area smaller than 0.16 mm².
▪ silicon proven in a 65 nm CMOS process.

Deliverables

▪ GDSII stream and layer map file;
▪ Library Exchange Format (LEF) file;
▪ Circuit Description Language (CDL) netlist;
▪ Liberty Timing File (.lib);
▪ VHDL behavioral model;
▪ design specification.
