TI-83 Plus Memory and Variable Management 626
If the
MEMORY
Screen Shows Enough Free Space
Even if the
MEMORY
screen shows enough free space to archive a
variable or store an application, you may still get a
Garbage Collect?
message or an
ERR: ARCHIVE FULL
message.
When you unarchive a variable, the
Archive free
amount increases
immediately, but the space is not actually available until after the next
garbage collection.
If the
Archive free
amount shows enough available space for your
variable, there probably will be enough space to archive it after garbage
collection (depending on the usability of any empty blocks).
The Garbage Collection Process
The garbage collection process:
•
Deletes unarchived variables from
the user data archive.
•
Rearranges the remaining
variables into consecutive blocks.
Note: Power loss during garbage collection may cause all memory (RAM and
Archive) to be deleted.
