TRANSISTOR DIELECTRIC RUPTURE TYPE ANTI-FUSE UTILIZING CHISEL OR CHISHL, AND PROGRAM CIRCUIT HAVING IT

摘要

PURPOSE: A transistor dielectric rupture type anti-fuse utilizing chisel or CHISHL, and program circuit having it are provided to program data under low voltage by destructing a dielectric adjacent to a drain of a transistor. CONSTITUTION: A substrate(15) has a first conductivity type. A source(13) and drain(14) have a second conductive type and are separated from a predetermined domain within a substrate. A dielectric(12) is formed between source and drain on the top of substrate. The transistor comprises a gate(11) formed on the top of the dielectric. The dielectric between the gate and the substrate which is adjacent to the drain is destroyed.
