While the temporary table is in-use, For a small table the data will be in the memory, For a large table if data is not fit in memory then data will be flushed to disk periodically as the database engine needs more working space for other requests.
A permanent table persist after terminating PostgreSQL session, whereas temporary table is automatically destroyed when PostgreSQL session ends.
The memory is controlled by temp_buffers parameter (postgresql.conf)
