Does anyone know what a TMS4050NL is, and an url for a data sheet? I just came across about 50 of them new, that were stored on static pads all these years.
TMS4050NL ?
4K x 1 dynamic RAM, according to one site. I would have guessed a dynamic ram controller, but the same page shows that the TMS4500 is the dynamic ram controller from TI.
I could find that with a websearch, I used yahoo. Of course, since the number made me think of the controller, I used "TMS4050NL dram" for the searchwords, which got rid of some of the clutter.
Given its size, a completely useless piece of memory unless you use it to repair an existing piece of equipment.
The datasheet is bound to be in a TI databook for memory, if you find one old enough. The one I have doesn't have anything close to something that small.

Just toss 'em out then, I guess?
That, or put them on E-bay for some collector of old equipment.

Ebay charges fees if they don't sell.
It's in my "MOS Memory Data Book" from TI dated 1978.
4Kx1 dynamic ram, open drain, 200/250/300ns access time grades. (With no suffix number I guess yours is the slowest.) Runs on +12V and -5V like many devices of that era. "Low power dissipation - 420mW typical" ;-)I could scan the entire datasheet (8 pages A5 size) if you like, let me know. Mike.
Thanks abyway, it sounds like they're totally worthless, I should just toss them.

Old low capacity memory chips (SRAM, DRAM, EPROM) seem to be in demand by restorers of arcade games, eg pinball machines.

Of course, really old memory is kind of neat to keep around, to show the grandkids.
"See this, it's a 256 by 1bit memory. When I was a kid, that's all we had." I was looking for something the other day and found my
1101 RAM, which is on that level of lack of memory, which I keep precisely to show it off.Of course, 4K by 1 DRAM comes much later, and is almost high density.

Hey, at work we're having a problem with our Dell GX-200s and similar. We've got a couple hundred, and they all use Rambus. Well we're finding out that the Rambus mem is getting difficult to find. And it's really expensive. Like a couple hundred dollars for a DIMM. Weird. Maybe we'll have to cannbalize some old machines to get memory for the others.
ababu?
That's ubaba spelled backwards. ;-)
