Abstract
There are provided a bias voltage generator, a semiconductor memory device having the bias voltage generator, and a method for generating the bias voltage. The bias voltage generator which generates the bias voltage to control a sensing current supplied to a memory cell for sensing data is characterized in that the bias voltage is output in response to an input voltage being applied, so that a slope of the bias voltage to the input voltage is different in at least two sections divided corresponding to a level of the input voltage.
