Need Help with Bluetooth

hello guys, I've been trying to make a bluetooth module, I've done a little bit research, I'm bit confused with them...
I'm trying to make a Bluetooth Speaker.

For the bluetooth Speaker i wanted to use the CSR8645 IC, the datasheet says it is a "Stereo ROM Solution with aptX", the reference design uses a I2C EEPROM or SPI Flash for storage of PS keys, even all the bluetooth modules I came across has this EEPROM, what actually is stored in the EEPROM?
Is it necessary? If so how can I build a module myself with the CSR8645 myself and write in the EEPROM?
