The multi-store model of memory is a conceptual idea about how memory in our species works.
In short, the multi-store model of memory proposes three different types of memory - Sensory memory; very short, few second long stimulus retainment of what we see and what we're actually attentive towards. This is then forwarded to what we call short-term memory where memory is being stored for a bit longer. With information we're storing in short-term memory we then transfer it to the so called long-term memory where supposedly it can stay for very long.
