Disclosed is a multi-channel memory device with an efficient power supply structure. The multi-channel memory device includes a first channel memory and a second channel memory which are independently accessed on the same chip. Also, the multi-channel memory device includes a decoupling unit which operationally separates the first and second external power source channel connection lines of the first and second channel memories in response to a decoupling driving signal, and a switching control unit which applies the decoupling driving signal to the decoupling unit in response to a channel power control signal to use external power independently applied to the first and second channel memories in the corresponding channels. An independent operation according to each channel is secured by independently comprising a power net according to each channel and power noise interference between the channels is removed or minimized. |
