Chapter 11 Memory Manager

This calculator includes main memory and storage memory for data storage.

The main memory is a work area where you can input data, perform calculations, and run programs. Data in the main memory can be deleted by batteries going dead or when you perform a reset.

Storage memory is an area for storing eActivity files, picture data (g3p files), and other relatively large-volume data. The storage memory uses “flash memory,” so data is safe even when power is interrupted. Normally, you should use the storage memory for data you need to store securely for long periods, loading data into the main memory only when you need it.
