That's not a radiation hardened chip, it's regular off-the-shelf consumer electronics. The "solar radiation" test they advertise is part of MIL-STD-810H. It tests whether the electronics survive regular sunlight on earth. The only ionizing radiation this phone is rated for is UV light.
At least if it had registered memory there might be an argument that it has some radiation resistance, but no it's plain old LPDDR4x.
Ulefone Armor 29 Ultra has the same MIL-STD-810H conformance with "radiation hardening", 16GB of RAM and a flagship Dimensity 9300+. Just not a removable battery.
Funny because the Qualcomm sm7450-ab snapdragon 7 gen-1 page lists itself as only supporting LPDDR5.
>also do you mean perhaps Strontium-90?
Nope. Strontium-60. 25 year half life compared to Sr-90's ~29. It's what we like to use in real space-environment testing on the ground. Nasty stuff.
>source?
You can actually probe your hardware and see what sort of ECC is enabled on a Droid phone. In this case, in-line ECC, so that means some of the RAM is actually sacrificed for error correction instead of having a dedicated extra chip (256 bit, 240 of that is data 16 bit is error correction.) What's awesome about that is that enabling ECC is simply a bit flip in firmware and you don't need the extra RAM modules installed - the installed memory can already do it. You don't need the extra hardware.
