Magnetic random access memory (MRAM)-based frame buffering apparatus, display driving apparatus and display apparatus including the same

A display apparatus comprising:

• a display panel configured to display an image;
• a display driving apparatus, coupled to the display panel, configured to control signals for driving the display panel, control storage of frame data according to an intensity of an external magnetic field, and provide a voltage corresponding to the image to the display panel;
• and
• a graphics processor configured to transmit input image data related to the image to the display driving apparatus,
• wherein at least one piece of frame data associated with the image is stored when the intensity of the external magnetic field is less than a threshold value;
• and
• wherein the at least one piece of frame data is transmitted to the display panel in real time if the intensity of the external magnetic field is greater than or equal to the threshold value.

A frame buffering apparatus comprising:

• a frame buffer memory including magnetic random access memory (MRAM);
• and
• a magnetic field sensor, coupled to the frame buffer memory, configured to sense intensity and direction of an external magnetic field applied to the frame buffer memory,
• wherein the frame buffering apparatus is configured store at least one piece of frame data in the frame buffer memory when the intensity of the external magnetic field is less than a threshold value;
• and
• wherein the frame buffering apparatus is configured to transmit the at least one piece of frame data to a display in real time if the intensity of the external magnetic field is greater than or equal to the threshold value.
