Memory Manager
Your calculator has two memory areas: Main Memory and Storage Memory.
The main memory is a work area where you can input data, perform calculations, and run
programs. Data in the main memory is relatively safe, but it can be deleted by batteries going
dead or when you perform a full reset.
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.
You can also load an SD card into the calculator's card slot and use SD card memory as well.
