How is the sign bit represented in memory and in cache?

I'm a dev, and I'm trying to use bitfields in my software, and I heard that intel store's it's sign bit in bit 7 (aka the 8th bit) regardless of the size of the datatype, and I was just wondering if that is true, and if not when it stopped being true?

Also, I've heard that data is stored in memory in little endian, but is flipped to big endian inside the CPU, and I'm just wondering if that's true, and where I can get better info about how intel cpus work?

There is a different room for developers at Intel communities.
