Quantum computing in the NISQ era and beyond (blog.acolyer.org)

I looked up Quantum RAM (QRAM) as has been discussed in the review, and I found the original work by Seth Lloyd. But I fail to find any architecture for the QRAM in the original paper.

Would someone knowledgeable enough kindly point me towards it?

Thanks :)

PS -> I've submitted the original QRAM paper in the HackerNews feed.
