Abstract

This is a storage system in which data are structured in a cellular way unlike typical systems in which data are coded. Each information pattern is related to the meaning of the concepts or relationships to be memorized and is not EBCDIC or ASCII coded. Pattern Representation Information is represented by a pattern I of n (e.g., 256) bits which can be formed: - randomly if the concept associated with the pattern is new and without relationship with other patterns - by an OR function of other patterns I1, I2... when the associated concept is related to other concepts already represented. I = (k1.I1) OR (k2.I2) OR ..... OR (kn.In) Operations on Patterns Assuming S is an input pattern to be compared with the memorized patterns Ik, three operations can be carried out.

Parallel Cellular Memory

This is a storage system in which data are structured in a cellular way unlike typical systems in which data are coded. Each information pattern is related to the meaning of the concepts or relationships to be memorized and is not EBCDIC or ASCII coded. Pattern Representation Information is represented by a pattern I of n (e.g., 256) bits which can be formed: - randomly if the concept associated with the pattern is new and without relationship with other patterns - by an OR function of other patterns I1, I2... when the associated concept is related to other concepts already represented. I = (k1.I1) OR (k2.I2) OR ..... OR
(kn.In) Operations on Patterns Assuming S is an input pattern to be compared with the memorized patterns Ik, three operations can be carried out. - upper pattern search (U) Uk = S AND Ik over Ik - lower pattern search (L) Lk = S AND Ik over S - search for closely related patterns (V) Vk = S AND Ik over S OR Ik Memory Organization

Each pattern Ij is stored in a cell having a size of n bits. The number n depends on the complexity of the information. All processing operations, such as logical operations, are simultaneously carried out on all cells of the memory . Applications The above cellular memory can be used in systems operating as a human brain. Indeed, each pattern provides an output signal which depends upon the relation existing between the input pattern S and the other patterns of the system. Further...
