Abstract
The present invention relates to a resistance variable memory device, and more particularly, to a resistance variable memory device capable of preventing an effect of coupling noise. The resistance variable memory device includes: a memory cell connected to a bit line; a precharge circuit precharging the bit line in response to a precharge signal; a bias circuit providing a bias voltage to the bit line in response to a bias signal; and a control logic controlling the precharge signal and the bias signal. The control logic provides the bias signal to the bias circuit at a precharge interval. Accordingly, the resistance variable memory device according to the present invention can prevent an effect coupling noise.
