In mental memory, storage is one of three fundamental stages along with encoding and retrieval. Memory is the process of storing and recalling information that was previously acquired. Storing refers to the process of placing newly acquired information into memory, which is modified in the brain for easier storage.

Memory storage may refer to: Psychological term for storage (memory) of mental states; Computer hardware that acts as a data storage device;
Magnetic tape, used for tertiary and off-line storage; Carousel memory (magnetic rolls). In early computers, magnetic storage was also used as: Primary storage in a form of magnetic memory, or core memory, core rope memory, thin-film memory and/or twistor memory; Tertiary (e.g. NCR CRAM) or off line storage in the form of magnetic cards;
The input comes from secondary and tertiary sensory areas that have processed the information a lot already. Hippocampal damage may also cause memory loss and problems with memory storage. [80] This memory loss includes retrograde amnesia which is the loss of memory for events that occurred shortly before the time of brain damage. [76]
Logic circuits without memory cells are called combinational, meaning the output depends only on the present input. But memory is a key element of digital systems. In computers, it allows to store both programs and data and memory cells are also used for temporary storage of the output of combinational circuits to be used later by digital systems.
This category is for articles having to deal with the faster forms of memory (like DRAM). For articles about slower forms of storage like disk storage , use the Category:Computer data storage . The main article for this category is Computer memory .
Molecular polymer storage has been shown to store 10 Tbit/in 2. [10] By far the densest type of memory storage experimentally to date is electronic quantum holography . By superimposing images of different wavelengths into the same hologram, in 2009 a Stanford research team achieved a bit density of 35 bit/electron (approximately 3 exabytes /in ...
