Survive: Pointer-Based In-DRAM Incremental Checkpointing for Low-Cost Data Persistence and Rollback-Recovery.

This paper introduces the Survive DRAM architecture for effective in-memory micro-checkpointing. Survive implements low-cost incremental checkpointing, enabling fast rollback that can be used in various architectural techniques such as speculation, approximation, or low voltage operation. Survive also provides crash consistency when used as the frontend of a hybrid DRAM-NVM memory system. This is ...
