The semiconductor memory which is used in the personal computer and the like (DRAM) at one of standard, DDR SDRAM standard of the 3rd generation who improves DDR2 SDRAM. Mainly it is utilized as main memory of the personal computer and the server.

As for the standard of DDR3 economic organization JEDEC of the electronic part was advancing standardization, first specification was announced in 2005. After that high speed specification is added from order.

As for DDR3 being maximum, (DDR of the identical clock is not) vis-a-vis SDRAM, high speed of 8 times data transfer has become possible. With former DDR2 SDRAM 4 times, DDR SDRAM (DDR1) with 2 times were highest. In addition, also decrease of electric power consumption advances, 1.5V operates low at voltage vis-a-vis 1.8V of 2.5V/2.6V and DDR2 SDRAM of DDR SDRAM.

DDR333 <PC2700>

Field:
Semiconductor > memory > RAM > DDR333

At one of types of the memory of DDR SDRAM, the external clock of 166MHz (FSB) the specification which corresponds.

PC2700 with standard of memory module, has shown the fact that maximum data rate is approximately 2.64GB/s. DDR333 with standard of the memory chip which corresponds, time data rate drive of 166MHz (DDR) has shown the fact that it is correspondence possible.

DDR3 SDRAM <DDR3>

DDR400 <PC3200>

Field:
Semiconductor > memory > RAM > DDR400

At one of types of the memory of DDR SDRAM, the external clock of 200MHz (FSB) the specification which corresponds.

As for PC3200 with standard of memory module, maximum data rate 3.2GB/s (3200MB/s) has shown the fact that is. DDR400 with standard of the memory chip which corresponds, time data rate drive of 200MHz (DDR) has shown the fact that it is correspondence possible.
