Help ID this Vintage RAM?

I have for some time been acquiring vintage dated parts for my A1 replica.   

 

A while ago there was a huge glut of 1977 vintage MK4027P-3 RAM available on eBay, and I bought 48 of them for about $20, ostensibly to use in my Newton-1, as I read it will work in place of the more appropriate Mk4096.

 

I also acquired a large quantity of MK5316P for $10 at about the same time.  Problem is, I can't seem to find a datasheet for the MK5316P.  I would presume it is an 16K x 1 DRAM, but I can find no information on it.  This particular batch dates to mid-1985.  Does anyone recognize this IC and/or be able to point me to a datasheet?

 

Here is a quick scan of a selection of the chips.

Thanks for your help in advance.

Mk5316

There is a MK5316 listed as a telecommunications (codec) device in the 1984 mostek data book.

I did find a reference to it

I did find a reference to it as a codec, but assumed I made a mistake because it didn't just look right.  Thank you for the link to that book.  That would have saved a lot of trouble.  Well then, it is not a DRAM at all.  Well, one more chip for the collection, I guess.  It was so inexpensive it is no real loss.
