The memory controller 13 may perform operations of writing, reading or erasing the data requested by the host 20 on the memory 15.

The buffer memory 16 may be used to temporarily store the data to be stored in the memory 15 and the data read from the memory 15. The buffer memory 16 may include, but is not limited to, a volatile memory such as a DRAM (Dynamic Random Access Memory).

The memory 15 may include a non-volatile memory such as a flash memory, an MRAM (Magnetoresistive Random Access Memory), a PRAM (Phase-change Random Access Memory), and a FeRAM (Ferroelectric Random Access Memory). Although the following embodiment shows an example in which the memory device 10 is an SSD (Solid State Drive) including a flash memory, the applicable embodiments are not limited thereto.

The aforementioned memory system may be built in or installed inside various electronic devices. The electronic devices are devices that include electronic equipment and electronic components, and may include, for example, a desktop PC, a tablet PC, a laptop PC, a netbook computer, a workstation, a server, a PDA, a mobile phone, a smartphone, a video phone, an electronic book reader, a MP3 player, a digital camera, a TV, a projector, a game console, a navigation device, a robot, a global navigation satellite system (GNSS), as well as medical equipment including electronic equipment, a washing machine, a refrigerator and the like. Further, in the case of an automobile, a drone, an aircraft, a ship, a satellite and the like, a device may also be called an electronic device as long as it includes electronic equipment or electronic components.
