related to Multi-channel memory architecture for computers

In the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the transfer speed of data between the DRAM memory and the chipset memory controller by adding more channels of communication between them. Theoretically this multiplies the data rate by exactly the number of channels present. Dual-channel memory employs two channels. The technique goes back as far as the 1960s having been used in IBM System/360 Model 91 and in CDC 6600.
