1. A memory system, comprising:
first and second memory devices, wherein the first memory device is a volatile memory device and the second memory device is a nonvolatile memory device; a first memory controller configured to control the second memory device, to store a request signal to access the first memory device, and to generate an interrupt signal; and a host configured to receive the request signal in response to the interrupt signal and to cause first data to be transferred from the second memory device to the first memory device, wherein first memory controller is configured to generate the interrupt signal if the first data is part of data that is divisionally stored in the second memory device and a buffer of the first memory controller.
