Abstract:
A repair signal generating circuit comprising:a power supply;a first p-channel transistor having a source, a gate, and a drain, wherein said source is connected to said power supply, and a reset signal is input into said gate;a fuse having a grounded first terminal;an n-channel transistor, having a source, a gate, and a drain, wherein said source is connected to a second terminal of said fuse, the reset signal is input into said gate, and said drain is connected with said drain of said first p-channel transistor;a second p-channel transistor having a source, a gate, and a drain, wherein said source is connected to said power supply, said drain is connected to said drains of said first p-channel transistor and said n-channel transistor, said second p-channel transistor having an on-resistance higher than that of said n-channel transistor; andan inverter having an input terminal and an output terminal, wherein said input terminal is connected to said drains of said first p-channel transistor and said n-channel transistor, and said output terminal is connected to said gate of said second p-channel transistor, said inverter outputting a repair signal from said output terminal.
