When to clear memory vs reset

Memory clear targets history, lists, or graph data. Factory reset removes apps, programs, and archived files — required before some proctored exams. Use our TI-84 Plus CE reset tutorial for All Memory wipes.

RAM vs Archive vs Apps

Storage What lives here Typical clear action
RAM Variables, lists, history, RAM programs ClrAllLists, DelVar, Reset RAM
Archive Archived programs and apps Delete from Mem Mgmt
Apps NoteFolio, Cabri, etc. Delete app or full reset

How to clear calculator history TI-84 Plus

On the home screen, scroll to an old entry and press CLEAR line by line, or clear RAM variables that store previous answers. For a fresh session before graphing, clear Y= lines you no longer need — see the graphing equations guide.

Clear variables and lists

  1. STAT4:ClrList → choose L1, L2, etc.
  2. Catalog (2nd0) → ClrAllLists for everything at once.
  3. DelVar X style commands remove single variables from the home screen.

Clear graph database and plots

Open Y= and press CLEAR on each line. Check 2ndSTAT PLOT and turn off unused plots. If the graph still looks wrong, ZOOM6:ZStandard.

Memory clear TI-84 Plus CE from the MEM menu

  1. 2nd+ (MEM).
  2. 2:Mem Mgmt/Del… to delete specific files.
  3. Run GarbageCollect from the catalog if archive space is fragmented.

Freeing space also helps before you transfer notes to TI-84 Plus CE with NoteFolio.

Common problems after a partial clear

  • ERR:INVALID DIM — list missing; re-enter data or clear the stat plot reference.
  • Still no graph — confirm plot is enabled and window fits the function.
