They made aircrafts and they haven't had anything to do with BRP for like 12 years 23 years and sold off the transportation (rail) division about 5 years ago.
That is not correct. The DRAM is not part of the same die that the SoC is on. It is separate packages directly beside the SoC. The storage is also separate packages.
If it was all one die it would be huge and have poor yields.
The core technologies that UTDC (then Bombardier, now Alstom) took from this is still being used all over the world. The new Vancouver SkyTrain is still using Linear Induction Motors.
Yeah their first two dedicated EV cars(for NAR anyways), ex30 and ex90, are pretty hated by most reviewers.
