Training about memory
In the morning, Mr King gave us training about memory including DDR and DDR2.
The differences between DDR and DDR2 is DDR2 run faster and has lower working voltage. Some type memory named Rambus, assumed by Intel in 2001, encapsulated in another way.Though Rambus failed in Chinese market in the past three years, many experts thought it will be useful in the future computer systems.
Samsung, Hyrix are the first line manufactor which have good reputation, their products sells very well. In fact, all memery are product in the same working line, however, just like the CPU, they are tested and given a mark as 400Mhz if it is very good, or 333Mhz if it is just OK, and so on.
Registy Memory has register chipset on the PCB which maybe 6 layers or 4 layers. The register chipset buffers the data put in the memory so that Memory will work more stable if a large number of memory would have been requested.
