Abstract

A trimming fuse circuit with a latch is disclosed. The trimming fuse circuit includes: a first CMOS transistor having a first PMOS and a second NMOS, wherein said first PMOS has a size smaller than that of said first NMOS; a second CMOS transistor having a second PMOS and a second NMOS, wherein said second PMOS has a size larger than that of said second NMOS, and still an input terminal of said second CMOS is cross-coupled with an output terminal of said first CMOS, furthermore, an output terminal of said first CMOS is cross-coupled with an input terminal of said second CMOS; and a fuse connected in between said input terminal of said first CMOS transistor and ground; thus, outputting an voltage high control signal from said output terminal of said first CMOS while said voltage high fuse is not burned-out; and outputting an voltage low control signal voltage low whiles said fuse is burned-out.
