CD-i 220/60 - Weird timekeeper chip?

I've got 3 CD-i players, I'm currently fixing them up a bit and installing sockets for the timekeeper chips so I can replace them when I find new ones. The one in my CD-i 220/60 is different than the other two (210/40, 470/20) - It has the numbers "432101" and "M5M5256CP-70LL" on them. It seems to be a regular chip on top of some thick socket. Anyone encountered this before, and how/with what do I need to replace it?

Hello @twburn

Thank you for reaching us. Can you please take a picture of this timekeeper?

I've attached the image of the chips. I unstacked them (didn't know there was another chip below the top one).

@rosewood has made a pretty cool work. Take a look:

Thanks, @omegalfa!

Yes, it's the 32 KB NVRAM solution by Dallas. You can read all about it (fix / substitute) in the NVRAM section of my article.
