memory-address register storage
1Memory address register — The Memory Address Register (MAR) is a CPU register that either stores the memory address from which data will be fetched to the CPU or the address to which data will be sent and stored. In other words, MAR holds the memory location of data that… …
2Memory data register — The Memory Data Register (MDR) is the register of a computer s control unit that contains the data to be stored in the computer storage (e.g. RAM), or the data after a fetch from the computer storage. It acts like a buffer and holds anything that …
3Memory management unit — This 68451 MMU could be used with the Motorola 68010 A memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware component responsible for handling accesses to memory requested by the CPU. Its… …
4Address space — In computing, an address space defines a range of discrete addresses, each of which may correspond to a physical or virtual memory register, a network host, peripheral device, disk sector or other logical or physical entity. A memory address… …
5Direct memory access — (DMA) is a feature of modern computers that allows certain hardware subsystems within the computer to access system memory independently of the central processing unit (CPU). Without DMA, the CPU using programmed input/output is typically fully… …
6Processor register — In computer architecture, a processor register is a small amount of storage available as part of a CPU or other digital processor. Such registers are (typically) addressed by mechanisms other than main memory and can be accessed more quickly.… …
7Storage violation — A Storage violation is an attempt at, or successful alteration ( or corruption ) of computer memory that is intended to have the special status of protected (that is not alterable at least in the current mode of operation).It normally applies to… …
8Computer data storage — 1 GB of SDRAM mounted in a personal computer. An example of primary storage …
9Magnetic-core memory — A 32 x 32 core memory plane storing 1024 bits of data. Computer memory types Volatile RAM DRAM (e.g., DDR SDRAM) SRA …
10Virtual memory — This article is about the computational technique. For the TBN game show, see Virtual Memory (game show). Virtual memory combines active RAM and inactive memory in disk form into a large range of contiguous addresses. In computing, virtual memory …
