If your word size is nominally ``9`` bits, you will need to round the word size to ``16`` bits as the next multiple of ``8`` and set ``word_size = 2`` as **OpenRAM** assumes that there are ``8`` bits in a byte. + +## What is the smallest ROM that can be produced? + +Currently the smallest ``ROM`` that can be produced is ``6`` words, each word having a size of ``1`` byte, with ``8`` bits per byte being the default assumed by **OpenRAM**. + ## What to do if OpenRAM encounters an error? When OpenRAM runs, it puts files in a temporary directory that is
