LPDDR4
1. Requires dual sample state mode for simultaneous read/write data capture.
2. Requires dual sample state or quad sample mode for simultaneous read/write data capture. Dual sample
state mode requires double probing of DQ over 2.5 Gb/s. Quad-sample state mode operates from a single
probe load.
