lpddr4x memq DQS信息电压

根据引用中的信息，LPDDR4X内部存在一个对DQS的延迟链，真正到达DQS采样DQ的逻辑处，其仍然能够保证DQS的toggle处于DQ总线眼图的中间位置。而引用中提到，LPDDR4X的DQS和DQ之间存在一个相位差tDQS2DQ。根据这些信息，LPDDR4X的DQS信息电压应该是根据供电电压(VDD)和延迟时间(tDQS2DQ)来决定的。具体的计算方法可以参考JEDEC标准中的公式，根据温度(T)和供电电压(V)的变化来计算延迟时间的变化。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
