1M x 4-bit DRAM 20-pin DIP

I'm searching for a source of a DRAM memory IC that would have the following specs:


20-pin DIP memory chips

(16) 1meg x 4-bit dips make up a bank of 8mb. Should be 60-ns Fast Page Mode non-parity



An example would be Toshiba TC514400AP-60.



Other manufacturers might use the following base part numbers:



Fujitsu MB : 814400 Goldstar GM : 71C4400 Hitachi HM : 514400 Hyundai HY : 514400 Micron MT : 4C4001 Mitsubishi M5M: 44400



Any idea where I could find these would be appreciated.



I'm even up to pulling the DRAM from some old boards, if I can find someplace that has boards that contain these chips. Maybe an old printer buffer memory card or something.



Thanks!

Thanks for the link.

With a few notable exceptions, it seems that the majority of the companies that findchips searches are those "allchips4u.com"-type of sites where you must fill out an RFQ form for each and every chip -- just to find out the cost. Then, there are large minimum orders (many are $250+) Furthermore, the chips you get from them are often pulls -- which might be the route I have to go here with trying to source old chips, but obviously new is better.

Google seems to hit on all those sites already, and I've never had good luck dealing with most of them.

Thanks anyways

Try Jameco.

And JDR Microdevices if they're still around, ditto B&D Enterprises
