Device for performing at least one medical action at a human or animal body via device over memory cleaning called by wear leveling

A device for performing at least one medical action at a human or animal body:

• wherein the device comprises an energy source and a computer;
• wherein the computer
• a) comprises a first erasable non-volatile memory comprising a data storage region, comprising a first set of valid data blocks, and a block allocation table comprising a valid allocation entry for each valid data block of the first set, and
• is configured for performing at least one application, the application being configured
• i) to control the medical action, and
• ii) to prioritize the medical action over a memory cleaning called by a wear leveling,
• wherein rewriting a valid data block of the first set according to the wear leveling comprises
• a) invalidating the valid allocation entry in the block allocation table for the valid data block to be rewritten;
• b) writing a further valid allocation entry for a further valid data block of the first set into a free allocation entry of the block allocation table;
• c) invalidating the valid data block of the first set to be rewritten, thereby obtaining an invalid data block of the first set;
• and
• d) writing the further valid data block of the first set into a free data block of the data storage region;
• wherein if one or both of the following conditions is/are fulfilled the memory cleaning is called:
• A. less than a minimum number of no free data blocks is available in the data storage region for step d),
• B. less than a minimum number of free allocation entries is available in the block allocation table for step b);
• wherein the memory cleaning comprises erasing a plurality of invalid allocation entries of the block allocation table or a plurality of invalid data blocks of the data storage region or both.

A process, comprising as process steps

• a) providing the device according to any of the preceding claims;
• and
• b) operating the device in consecutive cycles or tasks by using the computer,
• wherein each cycle or task is characterized by a duration, or by a portion of energy, or both,
• wherein operating the device includes prioritizing the medical action over a cleaning of the first erasable non-volatile memory in terms of the duration, or of the portion of energy left, or both.
