WebHowever, RAM is organised so that 32 bytes at a time will be transmitted between RAM and CPU, and those bytes must start at an address that is a multiple of 32 bytes. Therefore, the last five bits of the address are never used, and there are no address lines for those five bits. Web12 sep. 2024 · A byte-addressable CPU connected to such a memory array would not connect the least-significant bit of the CPU address registers (A0) to the least-significant address pin of the memory chips (A0) -- that would make things word-addressable.
Web1GB RAM has 1*1024*1024*1024 bytes in it. Say our architecture is 32 bit.
