A CIRCUIT FOR PREVENTING MALFUNCTION OF A SEMICONDUCTOR

摘要

PURPOSE: A circuit for preventing the malfunction of a semiconductor is provided to increase the stability and reliability of a semiconductor by correctly implementing the driving operation of a selective data transfer between a bit line and a input output line. CONSTITUTION: A connection part(230) is switched on by a column select signal in order to selectively interlink a bit line and input output line. A signal control unit(220) maintains the column select signal at a constant voltage in order to turn off the connection part. The signal control unit comprises an inverter and a switching element reversing the column select signal. The switching element is switched on with the output of inverter. The switching element selectively maintains the column select signal at a constant voltage.
