    en.wikipedia.org/wiki/Computer_memory

    Computer memory stores information, such as data and programs, for immediate use in the computer. [2] The term memory is often synonymous with the terms RAM , main memory , or primary storage . Archaic synonyms for main memory include core (for magnetic core memory) and store .

  3. Computer data storage - Wikipedia

    en.wikipedia.org/wiki/Computer_data_storage

    A piece of information can be handled by any computer or device whose storage space is large enough to accommodate the binary representation of the piece of information, or simply data. For example, the complete works of Shakespeare, about 1250 pages in print, can be stored in about five megabytes (40 million bits) with one byte per character.

  4. Non-volatile memory - Wikipedia

    en.wikipedia.org/wiki/Non-volatile_memory

    Other examples of non-volatile memory include read-only memory (ROM), EPROM (erasable programmable ROM) and EEPROM (electrically erasable programmable ROM), ferroelectric RAM, most types of computer data storage devices (e.g. disk storage, hard disk drives, optical discs, floppy disks, and magnetic tape), and early computer storage methods such ...

  5. Memory cell (computing) - Wikipedia

    en.wikipedia.org/wiki/Memory_cell_(computing)

    Computer memory used in most contemporary computer systems is built mainly out of DRAM cells; since the layout is much smaller than SRAM, it can be more densely packed yielding cheaper memory with greater capacity. Since the DRAM memory cell stores its value as the charge of a capacitor, and there are current leakage issues, its value must be ...
