Self-refreshing Multiple Valued Memory

This paper introduces a structure for self-refreshing multiple valued memory. The idea is to use structures having repeating patterns, to represent different saved values. Assuming a clocked repeating finite pattern, each pattern will repeat themselves after a finite number of clock pulses N, having N different phases. The values saved will be represented by both a pattern, and the phase of the pattern. The criterion for being self-refreshing is being fulfilled by resetting the pattern to a known value at least once every period. Some of these structures are quite possible to implement without a linear relation between the levels saved (radixes) and the number of transistors. This can make it competitive as memory for some certain multiple valued logic applications, being integrated between logic structures on chip
