What exactly does indicate it's a Maxwell Gen 2?

For DDR3, yes. DDR4 however can haz higher capacity Chips

It's possibly LPDDR4, which comes at lower volume and clock rates due to lower voltages (and thus lower power consumption). However, a console like the Switch could need the bandwith from high-speed RAM, at 3200Mhz in a 64bit connection in Dual Channel (which seems to be implemented considering they have each their own connections to the custom Tegra chip) it could reach 51.2 Gigabyte/s. If the connection is broader than 64bit (Xbox ONE connects it's RAM with a 256 connection, so it's doable, just not the standard), Bandwith could be much higher. at the aforementioned 256bit the bandwith would be ober 200GB/s in this particular case, way more than the chip could ever need.
My guess is it's (LP)DDR4-2133, but with a 128bit connection, giving a bandwith of 68GB/s, which should suffice for a console like the Switch.
