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. Examples are the various generations of SDRAM, and serial point-to-point buses like SLDRAM and RDRAM. An exception is the Fully Buff… WebMemory Mapped I/O. Isolated memory I/O is considered as a separate domain with comparison of memory. Considered as a part of memory. For application address space complete 1 MB memory is allowed. It takes only some part of the memory not the complete 1 MB memory. To map with other I/O operations, separate operations are provided.
