The system memory 2500 may store data used for an operation of the electronic device 2000. For example, the system memory 2500 may temporarily store data processed or to be processed by the main processor 2800. For example, the system memory 2500 may include a volatile memory such as a static random access memory (SRAM), a dynamic RAM (DRAM), or a synchronous DRAM (SDRAM), and/or a nonvolatile memory such as a phase-change RAM (PRAM), a magneto-resistive RAM (MRAM), a resistive RAM (ReRAM), or a ferroelectric RAM (FRAM).

The storage device 2600 may store data regardless of whether a power is supplied. For example, the storage device 2600 may include at least one of various nonvolatile memories such as a flash memory, a PRAM, an MRAM, a ReRAM, and a FRAM. For example, the storage device 2600 may include an embedded memory and/or a removable memory of the electronic device 2000.

The user interface 2700 may enable communication between a user and the electronic device 2000. In an example embodiment, the user interface 2700 may include input interfaces such as a keypad, a button, a touch screen, a touch pad, a gyroscope sensor, a vibration sensor, and an acceleration sensor. In an example embodiment, the user interface 2700 may include output interfaces such as a motor and an light-emitting diode (LED) lamp.
