  1. Vayamemory– TheDifferenceAmong DDR2,DDR3,andDDR4RAM DDR4RAMis thelatestgeneration of doubledata-raterandomaccess memory.DDR4MEMORYreplacesDDR3RAM,whichreplacedDDR2,which replacedwhatis nowcalledDDRRAM. Whatisdoubledata-ratememory? Doubledata-ratememorytransfersdatato theprocessoronboth therising and falling edgesof theclocksignal.Aclock signal is madeupofbotha downbeatandan upbeat.Usingboth beats to transferdatamakesdouble data rate memory significantly faster than single data-rate memory, which usedonlyoneedgeoftheclock signal totransferdata. Doubledata-rateisdifferentthandual-channelmemory,learnaboutdual-channel memory here. Memorygenerations Memorystandardsarecontrolled byJEDEC,theJointElectron Device EngineeringCouncil, an independentsemiconductorengineeringtrade organization andstandardization body.As each newgenerationof memoryis developed,this bodycontrolsthestandardsof thegeneration. Each generationofmemoryismarkedbyspeedandfrequencyincreasesand powerconsumptiondecreases.Becausecomputerhardwareisallconnected and interdependent,this leadstospeedincreases inothercomponents.

  2. Memory isNOT backwards compatible Oneofthereasonsforindustry-widestandardization in memoryis that computermakersneedtoknowtheelectricalparametersandphysicalshape ofthememorythatcan beinstalled in theircomputers.Becausetheelectrical parametersaredifferentforeachgenerationofmemory,thephysicalshapeof thememorychangestoprevent thewrong memoryfrombeing installed ina computer.Computers canuseonlythegenerationof RAMthat theyare designedfor.
