Bit vs Byte in memory adress?

I know that 1 byte = 8 bits.

  1. Can I access 1 bits in memory or it should be a full byte?

  2. Let's suppose the memory starts at: 0x0000 then what's the next position? 0x0001 or 0x0008?

Solution

  • It depends on how many bit processer you have. I don't think there are any 1-bit processors around.

    But a 8-bit processor would read a full byte, and then you can mask bits to actually read the only one you care about.

    Therefore, considering the most common architectures, the next address would be 0x0008

    Edit: Based on the comments, there are 1-bit processors
