Abstract
A bias voltage generating circuit supplies a bias voltage to a memory's bit lines. One end of a first transistor is connected to a first power supply. The first transistor conducts in response to a control signal. A second transistor is connected to another end of the first transistor. Another end of the second transistor and a gate of the second transistor are connected to an output node. One end of a third transistor and a gate connected to the output node. One end of a fourth transistor and a gate are connected to a second end of the third transistor. A second end of the fourth transistor is connected to a second power supply. One end of a fifth transistor is connected to the first power supply. The fifth transistor also conducts in response to the control signal. A sixth transistor is connected to a second end of the fifth transistor. A second end of the sixth transistor is connected to the output node and the gate of the sixth transistor is connected to a potential source. A seventh transistor is connected to the output node. A second end of the seventh transistor is connected to a ground potential. The seventh transistor also conducts in response to the control signal. The output node outputs a bias voltage to the bit lines when the control signal is activated, and is grounded through the seventh transistor when the control signal is non-activated.
