How many PIC pins does it normally take to support a serial
RAM chip?  What are the easiest SRAMS to use with a PIC?

        I can imagine that one could get away with two wires (clock
and data) if the SRAM requires a word of X bits with the first bits
being an address and the last 8 or so bits being data, but I have
never used one of these yet so I don't know what is available.

        In the present project, I need a SRAM of at least 8192 bytes
or 65536 bits.
