在数字电子产品以及电脑硬件领域，多信道内存技术（英语：Multi-channel memory technology）是一种可以提升内存数据发送性能的技术。它的主要原理，是在动态随机存储体和内存控制器/芯片组之间，增加更多的并列通信信道，以增加数据发送的带宽。理论上每增加一条信道，数据发送性能相较于单信道而言会增加一倍。目前常见的多信道技术多为双信道的设置，理论上它们都拥有两倍於单信道的数据发送带宽。这种技术最早可以追溯至1960年代的IBM System/360 91型电子计算机以及数据控制公司的CDC 6600型电子计算机。

In the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the data transfer rate between the DRAM memory and the 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.
