Memory, display device including the same, and writing method of the same

A display device, comprising:

• a master configured to provide an external signal;
• and
• a controller configured to output a data signal and a scan signal in response to the external signal,
• wherein the controller comprises a memory including an EEPROM, which stores an operation system and to be rewritable in response to a write operation signal, an address comparator, which is connected to I2C lines and outputs the write operation signal to the EEPROM in response to the external signal, a DAC unit, which determines whether to connect a DAC resistor and the I2C lines in response to the external signal, and a pull-up resistor unit, which is connected to the I2C lines.

A method of writing data to a memory, comprising:

• acquiring an external signal and determining whether the external signal is a write operation signal or a read operation signal;
• in response to a determination being made that the external signal is the write operation signal, opening up a connection between a DAC and I2C lines;
• and
• rewriting data to an EEPROM in response to the write operation signal,
• wherein the I2C lines are electrically connected to a pull-up resistor unit.

A memory, comprising:

• an electrically erasable and programmable read only memory (EEPROM) configured to store an operation system and to be rewritable in response to a write operation signal;
• an address comparator configured to be connected to Inter Integrated Circuit (I2C) lines and output the write operation signal to the EEPROM in response to an external signal;
• a digital-to-analog converter (DAC) unit configured to determine whether to connect a DAC resistor and the I2C lines in response to the external signal;
• and
• a pull-up resistor unit configured to be connected to the I2C lines,
• the EEPROM adjusts a resistance of the DAC resistor.
