Configurable serial memory interface

A method for rendering audio information stored on a removable memory device housed in a mobile communications device, the method comprising:

• receiving a request for audio information stored on a removable memory device;
• transferring the audio information to an audio rendering device through a configurable serial interface, wherein in a first mode the audio information is converted by a processing device operating above a predetermined rate;
• and in a second mode the audio information is converted by a separate converter when the processing device is operating below a predetermined rate;
• and
• rendering the audio information received from the first mode and/or the second mode through the audio rendering device in a user sensible format.

A mobile communications device comprising:

• a removable memory device housed at least partially within a port in the mobile communications device having a primary processing device, wherein the removable memory device includes audio information stored in a memory resident in the removable memory device;
• a processing device for converting the audio information from a digital state to an analog state for rendering by an audio rendering device in a first mode;
• a converter for converting the audio information from the digital state to the analog state for rendering by the audio rendering device in a second mode;
• and
• a configurable serial interface selectively operable to route the audio information from the removable memory device in the first mode or second mode depending on the status of the processing device.
