I red an article about DALLAS DS 1380/1381. It have 2k x 8bit.
It have two 8 bit Ports and 2 control lines. Over the first port
the PIC can supply Adress/Data. In a 'transparent' mode the 8
lines of the PIC can be switched through to the second port an
can be used as normal port pins. So you effective need two
pins on the PIC for the control signals.

I don't have any price information on this chip.
