Non-volatile memory device, driving method of memory controller controlling the non-volatile memory device and memory system including the memory controller and the non-volatile memory device
The present inventive concept provides a driving method of memory controller controlling nonvolatile memory device using variable resistive element. The memory controller may control a plurality of first memory devices and a second memory device. A number of write drivers in the second memory device may be driven when a number of first memory devices among the plurality of first memory devices are used. A different number of write drivers in the second memory device may be driven when a different number of first memory devices among the plurality of first memory devices are used.
