Hi,

To me the simplest way would be to add an EEPROM chip, this will allow you to easily rewrite all or any locations, and being non volatile you do not have to worry about saving the data before power off.

1 Mbit chips (128k x 1byte) are cheap enough and your Micro C should have a suitable module for it.

You can usually rewrite them 1 million times at least, data retention around 200 years.

Nothing to stop you using several of them, usually available with SPI or I2C inferfaces.
