  1. Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers. DDR SDRAM, also retroactively called DDR1 SDRAM, has been superseded by DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM and DDR5 SDRAM
  2. neskretsar för datorer. DDR SDRAM åstadkommer en högre bandbredd än vanliga SDRAM genom att överföra data på både stigande och fallande fas av klockcykeln. Detta innebär att dataöverföringshastigheten fördubblas utan att man behöver öka klockfrekvensen på Front side busen. Därför har ett 166 MHz DDR-system en effektiv klockcykelfrekvens på 333 MHz om man.
  3. When we introduced our DDR SDRAM, it was revolutionary and pioneering technology. DDR allows applications to transfer data on both the rising and falling edges of a clock signal, doubling bandwidth and vastly improving performance over SDR SDRAM. To achieve this functionality, we use a 2n-prefetch architecture where the internal data bus is double.
  4. Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM) is a common type of memory used as RAM for most every modern processor. First on the scene of this stack of acronyms was Dynamic Random-Access Memory (DRAM), introduced in the 1970s. DRAM is not regulated by a clock
  5. The next iteration of the SDRAM was the double-data-rate SDRAM (DDR SDRAM). Where the primary evolution came with the ability to transfer data on both the rising and falling edges of the master clock while all commands and operations took place only on the rising edge of the clock--effectively sending twice the data per clock cycle

grund av trycket från den nya DDR-SDRAM tekniken. Både Intel . och AMD har drivit behovet av minnesbandbredd till bristningsgränsen . med deras nya och krävande processorer. AMD har mer eller mindre gått . helt över till DDR-SDRAM och har helt klart varit en stark kraft bakom . DDR-SDRAM och dess framgång. Intel använder fortfarande SDRAM Det är DDR du ska titta på (Double Data Rate). (extra info: DDR SDRAM är eg det hela korrekta namnet på denna typ då ddr är en vidare utveckling så att säga av de gamla sdram minnena. SDRAM står för Synchronous Dynamic Random Access Memory) Om jag har fel gällande den extra infon här-så rätt mig gärna någon, jag kan minnas fel Det är ett DDR minne som du har. Dessa minnen finns på http://komplett.se/k/kl.asp?bn=10528. Man kan använda DDR-minnen av olika hastighet, du kan alltså använda PC2100 tillsammans med PC3200.

The memory also uses these clock signals to generate the DQS signal during a read via a delay-locked loop (DLL) inside the memory. The skew between CK or CK# and the SDRAM-generated DQS sign al is specified as t DQSCK in the DDR SDRAM data sheet. Table 2 DDR SDRAM is optimised to handle data packets from various in small bits with very low latency e.g browsers, programs, anti-virus scans, messengers. GDDR, on the other hand, can send and receive massive chunks of data on the same clock cycle

DDR SDRAM operates at data bus speeds (frequencies) of up to 400 MHz. At this frequency, 64-bit DDR SDRAM provides a theoretical peak bandwidth of 3.2 GB/s. The data bus can run at this frequency with the aid of strobes. However, the command bus does not use strobes and, therefore, must meet setup times to a synchronous clock ISSI is a technology leader that designs, develops, and markets high performance integrated circuits for the automotive, communications, digital consumer, and industrial and medical market.
