A Unified Information Phase Beyond Volatility Hierarchies

This paper establishes, at the level of principle, that the traditional separation between volatile memory and persistent storage is not a fundamental requirement of information systems. We demonstrate that uniform accessibility, long-term retention, reliable readout, and multi-state encoding can coexist within a single operational information phase without contradiction. The analysis is conducted independently of specific device implementations, focusing instead on admissibility under finite-temperature operation and conventional physical constraints. By removing the presumed incompatibility between access speed and persistence, the work shows that volatility hierarchies arise from historical design constraints rather than intrinsic properties of information. The results identify a unified information regime in which access semantics and data lifetime are no longer structurally differentiated. This establishes the foundational conditions for architectural, performance, and semantic unification examined in subsequent works.
