The archive memory is Flash-ROM

100000 cycles by sectors.

Normally the user data archive shouldn't be lost but as the variables
allocation table is stored in RAM you wouldn't be able to access your
archived varaibles any more. Once the RAM is lost,the TI-OS completely erase
the user data archive.
