rysi 1 signal to column redundancy line rys 1 of bank i and a second transmission gate 320 for receiving the bondij signal and inverted signal from the inverter inv and transmitting the rysi 1 signal to column redundancy line rys 3 of bank k referring to fig5 the seventh group 450 of the third multiplexer 400 receives bondkl signal and column redundancy select signal rysk 0 output signal of redundancy control block 600 including y fuse 500 comprising an inverter for inverting bondkl signal a first transmission gate 410 for receiving the bondkl signal and inverted signal from the inverter inv and transmitting the rysk 0 signal to column redundancy line rys 0 of bank k and a second transmission gate 420 for receiving the bondkl signal and inverted signal from the inverter inv and transmitting the rysk 1 signal to column redundancy line rys 3 of bank i when all the banks are normally operated bondij and bondkl signals are enabled to u2018 high u2019 level therefore rysi 0 signal column redundancy select signal in the second multiplexer 300 is loaded on column redundancy line rys 0 of bank i and rysi 1 signal is also loaded on column redundancy line rys 1 of bank i similarly rysk 0 signal column redundancy select signal in the third multiplexer 400 is loaded on column redundnay.
