Resetting All Memory
When resetting all memory on the TI-84 Plus, RAM and user data archive memory is restored to

Before you reset all memory, consider restoring sufficient available memory by deleting only
selected data.
To reset all memory on the TI-84 Plus, follow these steps.
1. From the RAM ARCHIVE ALL menu, press ~ ~ to display the ALL menu.
2. Select 1:All Memory to display the RESET MEMORY menu.
3. Read the message below the RESET MEMORY menu.
• To cancel the reset and return to the HOME screen, press Í.
• To continue with the reset, select 2:Reset. The message MEM cleared is displayed on the
HOME screen.
When you clear memory, the contrast sometimes changes. If the screen is faded or blank, adjust
the contrast by pressing y } or †.
Grouping and Ungrouping Variables
Grouping Variables
Grouping allows you to make a copy of two or more variables residing in RAM and then store them
as a group in user data archive. The variables in RAM are not erased. The variables must exist in
RAM before they can be grouped. In other words, archived data cannot be included in a group.
Once grouped, the variables can be deleted from RAM to open memory. When the variables are
needed later, they can be ungrouped for use.
To create a group of variables:
1. Press y L to display the MEMORY menu.
