memorys

Memorys is not a standard English word and is often seen as a misspelling of memories. This article uses memorys to refer to both human memory and computer memory—the ways information is stored and retrieved.

In humans, memory involves encoding, consolidation, storage, and retrieval. Working memory holds brief information; long-term memory stores it for longer periods. Long-term memory splits into declarative (episodic and semantic) and nondeclarative (procedural) forms. Key brain regions include the hippocampus, prefrontal cortex, amygdala, and cerebellum, which support encoding, retrieval, and skill learning. Memory is influenced by attention, depth of processing, sleep, and aging, and can be affected by disorders such as amnesia or Alzheimer's disease. Common memory errors include misattribution, forgetting, and memory distortions.

In computing, memory refers to devices for storing digital data. Primary memory, or RAM, is volatile and fast, for active programs. Nonvolatile storage such as SSDs or disks preserves data. Systems use a memory hierarchy: registers, caches (L1/L2/L3), main memory, and storage. RAM is mostly DRAM or SRAM; storage uses flash or disks. Performance depends on speed, latency, bandwidth, and reliability, managed by addressing and caching strategies.

Memory is a reconstructive process, not a perfect recording. Context, cues, and biases shape recall. In computing, memory design aims for speed, capacity, and reliability, using error correction, protection mechanisms, and caching policies.
