Apparatus and method for controlling power of external memory in mobile terminal

摘要

An external memory power control apparatus and method capable of controlling power of an external memory inserted into a mobile terminal. The external memory power control apparatus includes an external memory power switch for switching between a power supply and an external memory to supply or block power for the external memory; and a controller, when ‘power-on’ is selected on the mobile terminal, for checking and notifying operability of the external memory inserted into the mobile terminal after completing booting while the external memory power switch turned off, wherein the controller may selectively turn on/off the external memory power switch depending on operability of the external memory.

1. An apparatus for controlling power of an external memory in a mobile terminal, comprising:
a power switch for selectively supplying power to the external memory; and a controller for determining operability of the external memory inserted into the mobile terminal after booting responsive to a power-on of the mobile terminal while the power switch turned off and selectively supplying power to the external memory based on the detection outcome, wherein the controller further determines a state of the external memory power switch during a power-off of the mobile terminal, and if the power switch is on, the controller turns off the power of the mobile terminal after turning off the power switch.
