Difference between SQLite Temporary DB and InMemory DB

What is the difference between SQLite InMemory DB and Temporary DB ?

Reference: Temporary DB

While I expect Temporary DB is a disk backed file DB, the documentation is little confusing as it says temporary DB is almost same as in memory DB.

I am looking for a temporary disk file DB, where records are written to file on the disk. If temporary DB are stored as file on the disk, where do I find them ? I understand that when the connection is closed the DB cease to exist but while the connection is open I expect to find the DB on the disk.
