RAMtilaan

RAMtilaan is a proposed memory architecture discussed in theoretical and early-stage research on computer memory systems. It aims to blend the speed of conventional RAM with the persistence and durability of non-volatile storage, enabling data to remain intact without power while maintaining low latency.

Proposals describe RAMtilaan as a tiered or hybrid memory stack that uses a fast volatile layer paired with a non-volatile backing store, coordinated by an enhanced memory controller. The controller performs fine-grained wear leveling, data placement, and transactional guarantees to ensure consistency across power cycles.

Possible implementations rely on emerging memory devices such as resistive RAM or spin–orbit torque RAM, combined with novel error protection and wear management. Some discussions emphasize hardware-software co-design, including persistent memory APIs and programming models that treat RAMtilaan as a durable memory region.

Potential applications include in-memory databases, real-time analytics, large-scale caching, and systems requiring rapid recovery after power loss. RAMtilaan could shorten recovery times and simplify data persistence strategies, but it may introduce software complexity and higher hardware costs, depending on deployment.

As a theoretical concept, RAMtilaan has not been implemented in commercial products. Critics caution that achieving robust persistence without compromising latency or endurance is challenging, and that software ecosystems would need substantial adaptation to adopt persistent RAM semantics.
