DDR4及以前的内存上需要外围访问的device(SPD,Temperature Sensor)通常都是直接挂在到板子上(直连SOC的controller),到了DDR5,内存上集成了更多的设备,再通过直连的方式会让系统过于复杂,所以DDR5 内存引入了SPD HUB。 SPD HUB是一个挂在I2C/I3C总线下的hub device,自身包含了1024byte的SPD data,同时下面挂了更多DD...
The Rambus DDR5 SPD Hub (SPD5118-G1B) enables DDR5 Registered DIMMs, Load Reduced DIMMs, Unbuffered DIMMs and Small-Outline DIMMs.
