  2. Amiga Zorro III - Wikipedia

    en.wikipedia.org/wiki/Amiga_Zorro_III

    The CPU could directly address any Zorro III device as memory, so Zorro memory expansions could be made (and were made) as well as it being possible to use video memory on a video card to be as system RAM. As an asynchronous bus, Zorro III specified bus cycles of set lengths during which a transaction conforming to the specifications of the bus ...

  3. Uniform memory access - Wikipedia

    en.wikipedia.org/wiki/Uniform_memory_access

    Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.

  5. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    The table below shows values for PC memory module types. These modules usually combine multiple chips on one circuit board. SIMM modules connect to the computer via an 8-bit- or 32-bit-wide interface. RIMM modules used by RDRAM are 16-bit- or 32-bit-wide. [49] DIMM modules connect to the computer via a 64-bit-wide interface.

  6. Bus (computing) - Wikipedia

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

    The memory bus is the bus which connects the main memory to the memory controller in computer systems. Originally, general-purpose buses like VMEbus and the S-100 bus were used, but to reduce latency , modern memory buses are designed to connect directly to DRAM chips, and thus are designed by chip standards bodies such as JEDEC .

  7. Amiga Chip RAM - Wikipedia

    en.wikipedia.org/wiki/Amiga_Chip_RAM

    The shared RAM data bus is 16-bit on OCS and ECS systems. The later AGA systems use a 32-bit data bus controlled by the Alice coprocessor (replacing Agnus) and 32-bit RAM. The memory clock runs at double the rate on AGA systems. As a result, chipset RAM bandwidth is increased fourfold compared to the earlier 16-bit design. However, 32-bit ...

  8. RAM limit - Wikipedia

    en.wikipedia.org/wiki/RAM_limit

    The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory.

  9. Input–output memory management unit - Wikipedia

    en.wikipedia.org/wiki/Input–output_memory...

    In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...
