An "in-memory database" would have the same limits as memcached - both are limited to the size of physical RAM. memcacheDB uses an actual disk-backed database, so it has no such size limits. memcacheDB using OpenLDAP's MDB database uses a memory-mapped database - it is as fast as an in-memory database, but is not limited to the size of physical memory.
