Of course it does. You have speed-of-light delay and address line cascading 
to decode. The slowness isn't due primarily to accessing the memory cells. 
It's due to the cascade of gates you have to go thru to decode the address 
to figure out which cell. That's why video memory can be so much faster than 
CPU memory - there's an access pattern (the video beam scan) that can be 
used to speed up address decoding.
