Heap is no longer the accepted term for these kinds of tables in MySQL but it is still supported for backwards compatibility. The new accepted term is Memory and as the name suggest, Memory tables store their data directly in memory. Memory tables are used primarily as temporary tables. When you delete a row from a memory table, you do not free up space in the server memory. Space is only freed once the table is deleted.
