  2. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    Random-access memory (RAM; / r æ m /) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.

  3. Dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Dynamic_random-access_memory

    Dynamic memory, by definition, requires periodic refresh. Furthermore, reading 1T dynamic memory is a destructive operation, requiring a recharge of the storage cells in the row that has been read. If these processes are imperfect, a read operation can cause soft errors.

  4. Random-access machine - Wikipedia

    en.wikipedia.org/wiki/Random-access_machine

    In computer science, random-access machine (RAM or RA-machine) is a model of computation that describes an abstract machine in the general class of register machines. The RA-machine is very similar to the counter machine but with the added capability of 'indirect addressing' of its registers.

  5. Static random-access memory - Wikipedia

    en.wikipedia.org/wiki/Static_random-access_memory

    Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory ; data is lost when power is removed.

  7. Semiconductor memory - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_memory

    RAM (Random-access memory) – This has become a generic term for any semiconductor memory that can be written to, as well as read from, in contrast to ROM (below), which can only be read. All semiconductor memory, not just RAM, has the property of random access .

  8. DDR SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR_SDRAM

    The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as 16 banks, 4 bank groups with 4 banks for each bank group for ×4/×8 and 8 banks, 2 bank groups with 4 banks for each bank group for ×16 DRAM. The DDR4 SDRAM uses an 8n prefetch architecture to achieve high-speed operation.

  9. RAM drive - Wikipedia

    en.wikipedia.org/wiki/RAM_drive

    A RAM drive (also called a RAM disk) is a block of random-access memory (primary storage or volatile memory) that a computer's software is treating as if the memory ...
