Description
Dong Hoon Shin and co-authors build a similarity search chip in a 2026 paper. Hashing methods turn data into short codes so near matches can be found fast, but fixed cutoffs and wasteful analog coding have kept them off dedicated hardware.
Their design, named DASH, uses a grid of transistors paired with memory resistors that works in both analog and digital modes. In analog mode it projects data at random while maximizing code entropy and adjusting its own bias from the data. Digital mode then measures code distances cheaply. On synthetic three dimensional clusters the chip kept groups apart and raised code quality. On a large digit set it beat fixed hashing on recall and noise tolerance.
