Which memory technology allows simultaneous access to two memory modules?

Dual-channel memory technology allows simultaneous access to two memory modules. Dual-channel memory technology is actually a memory control and management technology that relies on the memory controller to theoretically double the bandwidth provided by two memories of the same specification.

Dual-channel memory technology allows simultaneous access to two memory modules.

Dual channel is to design two memory controllers at the Northbridge (also called MCH) chip level. These two memory controllers can work independently of each other, and each controller controls one memory. aisle. The CPU can address and read data in these two memories respectively, thereby doubling the bandwidth of the memory and doubling the data access speed accordingly (theoretically).

The popular dual-channel memory architecture is constructed of two 64bit DDR memory controllers, with a bandwidth of up to 128bit. Because the two memory controllers of the dual-channel system are independent and complementary intelligent memory controllers, they can operate simultaneously with zero waiting time for each other.

This complementary "nature" of the two memory controllers can reduce the effective waiting time by 50%, thereby doubling the bandwidth of the memory. Although this new specification is mainly a change on the chipset and motherboard side, the purpose of dual channel is also to solve the problem of memory bandwidth, so that the motherboard can reach a bandwidth of 6.4 even when only using DDR400 memory. GB/s.

Dual-channel is a new technology used in motherboard chipsets (Athlon 64 integrated into the CPU). It has nothing to do with the memory itself. Any DDR memory can work on a motherboard that supports dual-channel technology.

Dual-channel memory technology is actually a memory control and management technology that relies on the memory controller of the chipset to theoretically double the bandwidth provided by two memories of the same specification.

It is not a new technology. It has been used in servers and workstation systems for a long time. It only came to the forefront of desktop motherboard technology to solve the increasingly embarrassing memory bandwidth bottleneck problem of desktop computers.

A few years ago, Intel launched the i820 chipset that supports dual-channel memory transmission technology. It formed a golden partner with RDRAM memory, and its outstanding performance made it become the market leader for a while. The biggest highlight, but the defect of high production cost caused it to be poorly received and was eventually eliminated by the market.

Since Intel has given up support for RDRAM, the dual-channel memory technology of mainstream chipsets refers to dual-channel DDR memory technology
