According to the wiki, a bank refers to the secondary structure of a DRAM chip, which is different from the bank mentioned in the dmidecode
command. I am wondering what the relationship is between these two concepts and why they are using the same term?
Additionally, when I run the dmidecode
command on a certain machine, I find that there are 32 banks on the machine, even though it should have only 16 memory channels (2 * Intel 8352Y CPU = 2 * 8channel). Why would there be more banks than channel number? What is the relationship between the memory bank in here and the memory channel?
