Abstract: PURPOSE: A circuit of sensing the level of back bias is provided to change the switch on-off method corresponding to the working mode of a semiconductor memory device and prevent error from occurring at the peak current. CONSTITUTION: In a circuit of sensing the level of back bias voltage, a constant current generator(10) produces a constant current regardless of the fluctuation of a power supply(VCC). A switch(20) switches the constant current. A current distributor(30) distributes the constant current from the switch(20) using a current mirror responding to a first control signal(CON1). A switching current ridder(60) rids the high current generated at switching by sending the high current to the ground responding to a second control signal(CON2). A sensor sensing the level of back bias voltage(40) produces an output signal(DETA) after sensing the level of back bias voltage using the current distributed from the current distributor(30). And a switching controller(50) produces a switching control signal(DETSW) used for switching the switch(20), the first and second control signals(CON1,CON2).
