Retention: The insulating oxide layers prevent the electrons from leaking out quickly, allowing data to persist for 10+ years under normal conditions. Over time, wear from repeated program/erase cycles (limited to ~1,000-100,000 per cell depending on type) can degrade this insulation, which is why SSDs use wear-leveling algorithms in their controllers to distribute writes evenly.
hidden in the idea of derivatives is that the next state is not just a number, but an actual regex, which contains all the information to create the next one. this is a mechanism to encode arbitrary information in the state, and use it to implement lookarounds. the lookarounds that we support are a bit limited compared to backtracking engines, but they are still very powerful and useful in practice, and more importantly, they come with the same performance guarantees as everything else.

In 1996, David Deamer and Daniel Branton’s labs at UC Santa Cruz and Harvard collaborated on a paper showing that when an electric current runs through a nanopore, passing purine (A and G) and pyrimidine (T and C) DNA bases through the nanopore disrupted the current to different degrees. While the technique couldn’t yet discriminate between all four bases, the general idea for a new single-molecule sequencing method was there.
