I believe that it would be a 512MB chip.
If you are interested in achieving upto 1.5GB of RAM see the following site:
You can expect to pay about $500 for one of these beauties!
Remember, you may only upgrade certain Motherboards to this amount. If you are interested in seeing what memory is good for you & learning more about it, see the following site:

NEC has a 4 GIGABYTE memory chip, which seems to be the cutting edge of huge ram chip development.  You can't buy one for your PC (its still a research toy).

Here's NEC's press release about it:

There isn't any mention of NEC coming up with anything bigger since (I couln't find anything), and the only other company that has a chance of beating that, Siemens, doesn't mention anything on their site.

oldgreyguy, if they're the ceramic type with the metal cover on top, you can rip the top off them and use them as mono CCD camera arrays :-)
