> the read controller is cached. No need to read the same bit twice

This reads like an LLM hallucination to me. LLMs, when out of their depth, will just start gluing concepts it thinks are high value to other concepts.

After doing that, it throws in what it thinks is a high value rhetorical snippet -- "no need to read the same bit twice" -- because, you know, that's what caching's all about, avoiding redundant reads of single bits. Man, I can't count how many times I read a particular bit twice and was like, "shoot, there was no need to do that". I can just picture a totally human not-an-LLM researcher coming up this sentence concerning tech that stores a claimed >3,000,000,000,000,000 bits per square centimeter.
