    摘要: A voltage clamping circuit for a semiconductor memory device which is capable of rapidly coping with the demand of the user. The voltage clamping circuit includes PMOS transistors connected in series between an external supply voltage terminal and a node on an output line of a DC voltage generator, a control PMOS transistor having a channel connected at both ends thereof respectively to the node on the output line and a node between the second and third ones of the series-connected PMOS transistors, and a pad connected to a control electrode of the control PMOS transistor. The pad is selectively connected to a supply voltage in a first state and to a ground voltage in a second state, thereby controlling a clamping interval of the clamping means to be variable. The first state is a state requiring a longer clamping interval than that of the second state.

    摘要: The present invention relates to a fuse option circuit of an integrated circuit and a method thereof. More particularly it concerns a fuse option circuit comprising: a first fuse formed on a chip, which is cut by providing a larger electric current than a set value; a second fuse formed on the chip identically with the first fuse; a fuse cutting means providing a cutting current loop to the first fuse in response to a fuse cutting signal; and an option signal generating means which produces a fuse option signal by comparing resistance values of the first and second fuses. Accordingly, even if the first use is abnormally cut, the fuse option can be precisely provided by comparing the first fuse having a changed resistance after cutting process with the second fuse keeping an initial resistance value. Therefore, the reliability of a fuse option of an integrated circuit can be improved.
