1Memory scrubbing — is the process of detecting and correcting bit errors in computer memory by using error detecting codes like ECC. Contents 1 Motivation for scrubbing 2 ECC support for scrubbing 3 Scrubbing in more detail …
2Memory 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… …
3Memory 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 …
4Memory architecture — describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information. Depending on the specific… …
5Bit rot — Bit rot, also known as bit decay, data rot, or data decay, is a colloquial computing term used to describe either a gradual decay of storage media or the degradation of a software program over time. The latter use of the term implies that… …
6Memory timings — (or RAM timings) refer collectively to a set of four numerical parameters called CL, tRCD, tRP, and tRAS, commonly represented as a series of four numbers separated with dashes, in that respective order (e.g. 5 5 5 15). However, it is not unusual …
7Bit blit — ( bitblt , blitting etc.) is a computer graphics operation in which several bitmap patterns are combined into one using a raster operator .OriginsThe name derives from the BitBLT machine instruction for the Xerox Alto computer, standing for Bit… …
8Memory Mapped I/O — (MMIO) (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… …
9Memory ProteXion — Memory ProteXion, found in IBM xSeries servers, is a form of redundant bit steering . This technology uses redundant bits in a data packet to recover from a DIMM failure. Memory ProteXion is different from normal ECC error correction in that it… …
