发明名称 CHIP INFORMATION OUTPUT CIRCUIT
摘要 PURPOSE: A chip information output circuit having a fuse box is provided to increase layout efficiency without affecting the input capacitance. CONSTITUTION: A chip information output circuit(100) includes N fuse blocks(FBLK1-FBLKN) that generate different outputs according as a fuse is cut or not, and a pipeline circuit(150) for receiving a plurality of signals output from the fuse blocks in parallel to serially output the signals sequentially. The chip information output circuit further has an output driver(170) and a pad(180) The pipeline circuit has a plurality of serially connected latches for latching the signals output from the fuse blocks. Each of the fuse blocks has multiple fuse boxes(FB1,FB2,FB3) which generate output signals having different phases based on the cut state of fuses contained therein. Each of the fuse boxes is enabled in response to a predetermined control signal and output lines of the fuse boxes are connected through a logic OR.
