But in DDR4 there is no voltage divider circuit at the receiver. It instead has an internal voltage reference which it uses to decide if the signal on data lines (DQ) is 0 or 1. This voltage reference is called VrefDQ. The VrefDQ can be set using mode registers MR6 and it needs to be set correctly by the memory controller during the VrefDQ calibration phase.

这意味着，要控制一个变量呈N²爆发的复杂系统，控制者自身必须具备同等维度的多样性。传统的“科层制+会议对齐”模式，其产生的“管理多样性”在量级上已无法匹配物理世界的“业务多样性”。这并非管理者的失职，而是触碰了控制论的物理极限。我们当年的突破在于：不再试图强行简化复杂度，而是通过 IPC（智能计划与控制）算法内核，构建出一个足以吸收物理世界复杂性的“数字多样性”。
"We never thought we'd see these episodes again. It was a real factory process, no time for post-production or anything like that, never repeated, never sold abroad.
