Abstract: In a method of operating a memory device, a first write command, a first write address, and first write data are received by a first memory device through a channel. The first write command, received by the first memory device, is sensed by a controller. The controller is connected to the channel and controls a second memory device. The first memory device and the second memory device are different types of memory devices. When the first write command is sensed by the controller, a first write log is generated using the first write address and the first write data. The first write log is stored into a buffer.
