OPTION FUSE CIRCUIT USING STANDARD CMOS MANUFACTURING PROCESS

摘要

An option fuse circuit using standard CMOS manufacturing processes includes a latch for latching signals, which includes a first node and a second node. The option fuse circuit also includes a comparator, which includes two input nodes and an output node. The comparator receives signals input at the two input nodes from the first and the second nodes, and compares the two signals in order to output a comparison signal. The option fuse circuit further includes two logic cells for storing non-volatile data. The logic cells include a word line node and a bit line node. The word line nodes are electrically connected to the output node of the comparator, while the bit line nodes are electrically connected to the first and the second nodes, respectively.
