Voltage of a memory of Micron DDR3 and DDR3L

Hi, I'd like to ask the next.

I've noticed that the memory that uses my evalutaion board is  a Micron memory. Also I've noticed that there exist DDR3 and DDR3L, where DDR3L works at 1.35V and DDR3 at 1.5V. The datasheet of a Micron for example (https://4donline.ihs.com/images/VipMasterIC/IC/MICT/MICT-S-A0003060424/MICT-S-A0003060424-1.pdf?hkey=52A5661711E402568146F3353EA87419) says that the memory is DDR3L but it is backward compatible with 1.5V. So from this, I understand that the DDR3L can be used at 1.5V. But what changes? Can I simple change the voltage of the DDR3L to 1.5V and I can use the same hardware description (that was uses in a DDR3) or something need to be changed?

thanks

@jose09621 Hi,

 

Yes, your understand is correct. You can install the DDR3L devices on the board which is designed for DDR3 devices. They are compatible.
