Neuroscience-based memory framework vs. simple embedding-based store.
March 2026
15 algorithms (9 + 6 PMA), 7 memory layers, Sleep Consolidation, FSRS
Simple key-value store with embedding search
ZenBrain is built on neuroscience research and implements 15 algorithms (9 foundational plus 6 PMA components) across 7 memory layers — including Sleep Consolidation, Two-Factor Synaptic KG, vmPFC-FSRS, Reconsolidation, and Neuromodulation. Mem0 offers a simple but effective key-value memory store with embedding search. For complex memory requirements, ZenBrain is the significantly more capable choice.
