Abstract: PURPOSE: An input/output circuit and a current control circuit of a semiconductor memory device are provided to prevent leakage of current in a test mode such as a burn-in test by forming the input/output circuit and the current control circuit insensitive to a change of a fabrication process, a variation of a voltage level of an input/output pin, and a variation of temperature. CONSTITUTION: The first and the second transfer portions(33,34) are formed by CMOS transfer gates. The first transfer portion(33) transfers low voltage(VOL) of the first input/output pin(31) in response to a current control enable signal(CCE). The second transfer portion(34) transfers high voltage(VOH) of the second input/output pin(32) in response to the current control enable signal(CCE). A voltage distributor(35) generates a mean value of the low voltage(VOL) and the high voltage(VOH). A comparator(36) compares the mean value(Vcmp) with reference voltage(Vref). A current control counter(37) generates control bits(ICTR0-ICTR5) in response to an output of the comparator(36). Resistances(R33,R34) of the first and the second transfer portions(33,34) are used for preventing leakage of current.
