For the small set of symbols covered here here, a direct addressed parallel memory based approach may be better. I suggest using a few memory cells technology based on an organo - chemical storage medium. Interfacing to the individual cells can be made with low level electrical signals; such as those that may be generated by, for example, dual stereoscopic visual or audio sensors. Programming the memory can be difficult, often write times are measured in weeks and in some cases even years, but once programmed can usualy be regarded as non-volatile provided several refresh cycles are made from time to time. Read time is variable and often depends on time of day, the total number of read cycles ever made over the life span, and the age of the memory cells.
