I don't think they do.
Why do you want to discharge?

Dis-charging lithium batteries to empty can actually harm them, that's why any decent mod will cut power at about 3.3v. Keep them charged at all times bomber and if you are going to store them make sure you charge them first  |

Yeah, you should fully use or discharge batteries before charging.

Battery memory was from the days of Ni-Cads. It was a bit of a myth really as the effect was quite rare and specific to some applications. There was all sorts of weird stuff done with Ni-cads to get an extra 1% or even less out of them.
As the others have said Lithium is a total different chemistry. Deep discharge and overcharge are a real no no. they really do prefer to be topped up.
