Magnetic Random Access Memory (MRAM)-Based Frame Buffering Apparatus, Display Driving Apparatus and Display Apparatus Including the Same

摘要

Magnetic random access memory (MRAM)-based frame buffering apparatus are provided that may reduce a size and power consumption thereof by using a pixel self-refresh (PSR) method. The MRAM-based frame buffering apparatus includes a frame buffer memory including magnetic random access memory (MRAM). The frame buffer memory stores at least one piece of frame data. The MRAM-based frame buffering apparatus further includes a magnetic field sensor configured to detect an external magnetic field; and a frame buffer controller configured to control the storing of the at least one piece of frame data according to the intensity of the detected external magnetic field.
