I don't know anything about TLBs but the M1 is a system on a chip, you can get up to 64GB of RAM shared between CPU and GPU all on the same die.

More specifically, it's a system on a _package_. A TLB lives on the _die_, though, with one in each core.

TLB cache isn't the same thing as the unified memory on the M1.
