- ORRAM is a RAM generator built into OpenROAD that uses standard cells, avoiding the need for custom bitcells or external tools.
- It solves memory inference challenges in ASIC flows by creating placed and routed RAM blocks with timing verified via OpenSTA.
- Features include support for arbitrary word sizes, word counts, multi-port reads, column muxing, latch-based storage, and PDK-agnostic cell selection.
- Evaluation on SkyWater 130nm shows it matches DFFRAM bit density while offering a broader feature set, with source code available in OpenROAD.
