Display device

A display device comprising:

• an external memory device disposed on a printed circuit board region, wherein the external memory device stores a first integrated circuit driving information;
• an internal memory device disposed in an integrated circuit region, wherein the internal memory device stores a second integrated circuit driving information generated by copying the first integrated circuit driving information, and the internal memory device comprises a power clamp circuit which detects an electrostatic discharge current;
• a buffer disposed in the integrated circuit region, wherein the buffer receives the second integrated circuit driving information;
• an error correction code calculator disposed in the integrated circuit region, wherein the error correction code determines a first error correction code of the first integrated circuit driving information and a second error correction code of the second integrated circuit driving information when the electrostatic discharge current is detected;
• and
• an error correction code comparator disposed in the integrated circuit region, wherein the error correction code compares the first error correction code and the second error correction code,
• wherein the internal memory device selectively updates the second integrated circuit driving information to the first integrated circuit driving information based on a result of a comparison of the first error correction code and the second error correction code.
