Inventor: YOSHIOKA SHIGEO
IPC: H02H9/04
Filed: 1990-11-27
Abstract: PURPOSE:To make a safer protective function to an overvoltage and an overcurrent without losing the spring property even though a surge is applied repeatedly, by making a metal part with a spring property and a part to fuse when an overvoltage or an overcurrent invades in the separate structures. CONSTITUTION:A metal wire 6 is fused instantly when a large current of overvoltage or overcurrent is applied, and when the current is a small one, a low melting point metal 5 is fused by the heating of a surge absorption element 7, and the circuit is opened by the springing effect of a metal wire 8. The wire 8 furnishing the spring property has a sufficient section area to generate no annealing effect when a surge invades, and even though a continuous and low surge invades to the element 7 to generate a heat, the heat is not delivered up to the wire 8, and its spring property is maintained. As a result, even in case the surges invade repeatedly, the wire 8 does not receive the influence of annealing effect, and does not lose the spring property, and when the metal 5 is fused, the wire 8 is sprung up to open the circuit.

Title: Semiconductor integrated circuit, memory module, storage medium, and relief method of semiconductor integrated circuit
Inventor: HIRAKI MITSURU
IPC: G11C11/401
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To improve a relief efficiency for a defect in a large-scale integrated circuit. SOLUTION: A large-scale integrated circuit includes a central processing unit 10, an electrically rewritable non-volatile memory 11 and volatile memories 12, 13 (the above elements share a data bus 16), and utilizes information stored in the non-volatile memory for defect relief of the volatile memories. The volatile memories respectively include volatile storage circuits 12AR, 13AR for latching relief information to be used for relieving a defect normal memory cell with a redundant memory cell. The non-volatile memory reads out the relief information from the non-volatile memory in response to an instruction for initializing the semiconductor integrated circuit. The volatile storage circuits latch the relief information from the non-volatile memory in response to the initialization instruction.  Accordingly, a fuse program circuit for defect relief can be eliminated, and a defect having occurred after a burn-in process can be further relieved. Thus, even after being mounted onto a circuit board, a new defect can be relieved.

Abstract: PURPOSE:To compensate the formation of a transition layer having narrow forbidden band width on a heterozygous interface and to obtain a high speed optical semiconductor device by interposing a third compound semiconductor layer having a specific composition between compound semiconductor layers having second forbidden band width wider than first forbidden band width. CONSTITUTION:The composition of a compound semiconductor material can be shown by A1-xBxCyD1-y, and A and B are a group III element, C and D are a group V element, and the forbidden band and lattic constant of a material is decided by the values of the compositions x and y.
