JEDEC JESD8-22 2009-AUG-01 HSUL_12 LPDDR2 O
This standard defines the input, output specifications and ac test conditions for devices that are designed to operate in the High Speed Unterminated Logic (HSUL_12) logic switching range, nominally 0 V to 1.2 V. The standard may be applied to ICs operating with separate VDD and VDDQ supply voltages.
