It sounds to me as if he was talking more RAM (Random Access Memory) as well
as regular memory, which in this case would probably be like EPROM (Electronic Programmable Read Only Memory). Think short term and long term memory, like 'Where did I leave that oil filter, I just bought' and 'How do I change my oil'. If you can hold more things in short term memory i.e. where is your oil, filter, and which socket you need for the drain plug? You can change your oil that much faster, well the same is mostly true for computers.
