What is the difference between DDR and DDR2 memory?
What is the difference between DDR and DDR2 memory?
The two factors combine to produce a total of four data transfers per internal clock cycle. Since the DDR2 internal clock runs at half the DDR external clock rate, DDR2 memory operating at the same external data bus clock rate as DDR results in DDR2 being able to provide the same bandwidth but with better latency.
What is the maximum capacity of a DDR2 memory card?
The maximum capacity on commercially available DDR2 DIMMs is 8GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used. DDR2 SDRAM was first produced by Samsung in 2001.
What is the difference between DDR SDRAM and DDR2 SO-DIMM?
DDR SDRAM for notebook computers, SO-DIMMs, have 200 pins, which is the same number of pins as DDR2 SO-DIMMs. These two specifications are notched very similarly and care must be taken during insertion if unsure of a correct match. Most DDR SDRAM operates at a voltage of 2.5 V, compared to 3.3 V for SDRAM.
What is the maximum transfer rate of DDR3 SDRAM?
With data being transferred 64 bits at a time per memory module, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bits in a byte). Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s.
What is the comparison of DDR2 SDRAM standards?
Comparison of DDR2 SDRAM standards Name Name Name Chip Chip Standard Type Module Clock rate ( MHz) Cycle time ( ns) DDR2-400 B PC2-3200 100 10 DDR2-400 C PC2-3200 100 10 DDR2-533 B PC2-4200* 133 7.5
Where are the main locations in RDR2?

What was the first product to use DDR2 technology?
The first commercial product to claim using the “DDR2” technology was the Nvidia GeForce FX 5800 graphics card. However, it is important to note that this GDDR2 memory used on graphics cards is not DDR2 per se, but rather an early midpoint between DDR and DDR2 technologies.
