3-6. Memory

Memory structure consists of the following five memory blocks.

1.Set memory

2.Status memory

3.Channel memory

4.Chroma memory

5.W/B memory

CPU internal ROM : 256 kbyte Flash Memory

CPU internal ROM : 16 kbyte

External NVM memory : 8 kbyte EEPROM

Gamma memory is actualized through Gamma mode functions’offsetting the output values to the Contrast and Brightness devices.

When the power plug is connected to the power line (Standby status), all data inside the internal ROM are written into the NVM (Nonvolatile Memory). When the power is turned to on, required data for the current picture, such as status memory data, etc., are selected, and they are written into the internal RAM.

When adjustment is carried out, adjustment data are written into the NVM automatically (items on the user mode) or by the trigger of memory operation (items on the service mode and factory mode), then stored them. Adjustable items (W/B and Device Adjust) of the service mode and special service mode are memorized into the NVM by the memory operation. At the same time, the factory preset (adjusted) data are all eliminated from the memory.
