• Memory bus — The memory bus is the computer 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… …   Wikipedia

• Memory bandwidth — is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second, though this can vary for systems with natural data sizes that are not a multiple of… …   Wikipedia

• Bus (computing) — 4 PCI Express bus card slots (from top to bottom: x4, x16, x1 and x16), compared to a 32 bit conventional PCI bus card slot (very bottom) In computer architecture, a bus is a subsystem that transfers data between components inside a computer, or… …   Wikipedia

• Memory address — A digital computer s memory, more specifically main memory, consists of many memory locations, each having a memory address, a number, analogous to a street address, at which computer programs store (except when the address is in mask ROM) and… …   Wikipedia

• Memory geometry — In the design of modern personal computers, memory geometry describes the internal structure of random access memory. Memory geometry is of concern to consumers upgrading their computers, since older memory controllers may not be compatible with… …   Wikipedia

• Bus sniffing — or Bus snooping is a technique used in distributed shared memory systems and multiprocessors to achieve cache coherence. Although there is one main memory, there are several caches (one per processor), and unless preventative steps are taken, the …   Wikipedia

• Bus contention — Bus contention, in computer design, is an undesirable state of the bus in which more than one device on the bus attempts to place values on the bus at the same time. Most bus architectures require their devices follow an arbitration protocol… …   Wikipedia

• Memory type range register — Memory type range registers (MTRRs) are a set of processor supplementary capabilities control registers that provide system software with control of how accesses to memory ranges by the CPU are cached. It uses a set of programmable model specific …   Wikipedia

• Memory storage density — is a measure of the quantity of information bits that can be stored on a given length of track, area of surface, or in a given volume of a computer storage medium. Generally, higher density is more desirable, for it allows greater volumes of data …   Wikipedia

• Memory mapped I/O — (deutsche Übertragungen wie speicherabgebildete Ein /Ausgabe oder speicherbezogene Adressierung konnten sich bislang nicht durchsetzen) ist ein Verfahren zur Kommunikation einer Zentraleinheit mit Peripheriegeräten. Die I/O Register von… …   Deutsch Wikipedia

• Memory protection — is a way to control memory access rights on a computer, and is a part of most modern operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug… …   Wikipedia
