I missed this point when you posted. You do have an elegant idea, here. No, you're mind is not just electrons and the idea of linking electrons through quantum mechanics is quite a stretch. Even in modern computers, the binary states are maintained by energy wells with a relative change in charge - either positive or negative. To say your cybernetic implants keeps your thoughts as electrons is niaive.
On the other hand, who knows how computers will work 200 years from now. Even today we are experimenting with quantum computing. There definitely are quantum processes in physics that generate quantum pairs that are linked in space and time. If I understand the theory correctly, the spins of the two particles are indeterminant until you attempt to measure the spin of one of the particles. As we all know, the act of measurement alters the future of that particle, but the spin of the other particle will also be determined at the same time, even if it is lightyears away. Let us assume that the marine's cybernetic implants use some sort of quantum process for storing data. In accessing a pattern buffer, it might be possible to generate quantum particle pairs, with one half of each pair remaining in the pattern buffer and the other half in the marine's implants. When the marine dies, a mechanism would be invoked that would measure the spins of the quantum particles in such a way that they would contain the marine's memories. The pattern buffer, no matter how far away in space or time, would then contain the marine's future memories, which he could then download.
It's a bit far fetched, but I like this theory and it has some plausability, particularly if we accept other far fetch concepts such as FTL travel and teleportation. This also allows us to reconcile Bungie's explanation with what happens. The marine does indeed upload his pattern in the form of quantum pairs, but he also downloads that pattern with updated memories in the event that he dies.
