Minnesnivå

Minnesnivå is a Swedish term that translates roughly to “memory level.” It is used in different disciplines to describe the amount, depth, reliability, or accessibility of memory, whether referring to human memory or to information storage in computing. The concept is contextual and depends on the task, measurement approach, and technological or physiological conditions at play.

In psychology and cognitive science, minnesnivå describes the capacity and accessibility of memory for a given task. This encompasses distinctions between working or short-term memory and long-term memory, as well as how encoding, attention, practice, retrieval cues, and aging or neurological conditions influence memory performance. Researchers assess minnesnivå using various tests that measure recall, recognition, and learning across different material and time intervals. Results are task-dependent and vary across individuals.

In computer science and information technology, minnesnivå is used to refer to levels within a memory hierarchy. Typical levels include registers and cache memory (often labeled L1, L2, L3), main memory (RAM), and secondary storage (solid-state drives or hard drives). Each level offers different latency, bandwidth, and persistence, shaping how software and hardware optimize data locality and performance through caching, prefetching, and efficient memory access patterns.

Etymology: minne means memory and nivå means level in Swedish. The term appears in Swedish-language discussions of both cognitive performance and computer architecture. See also memory, working memory, cache memory, and storage hierarchy.
