The four categories of NoSQL databases
And no mention of memcache in the key/value list. Not cool enough anymore?

Indeed. Memcached is very effective for what it does and IMHO one of the fathers of the whole NoSQL thing.

I thought they left it off because it wasn't persistent.

This is just a particular tradeoff IMHO. It is persistent as long as the process is running. Other databases are persistent as long as the HD is working :) Others are persistent as long as N nodes are still working. Just tradeoffs.

While technically possible to accept in some cases, nowhere-durable is a rather extreme tradeoff option.
It would be interesting to reconsider memcached as durable storage in the modern SSD era, however.
