Bit addressability
Webaddressability then the least significant memory line is unused, –if the width of read/write operations is 4 times greater than the number of bits in addressability then the two least significant memory lines are unused, etc. • Note, it doesn’t make sense to have the width of read/write operations smaller than addressability. WebThe 64-bit address space also includes the virtual line at the 16-megabyte address; additionally, it includes a second virtual line called the bar that marks the 2-gigabyte address. The bar separates storage below the 2-gigabyte address, called below the bar, from storage above the 2-gigabyte address, called above the bar .

WebThe original MVS™ (pre zOS) architecture defined storage addresses as 24 bits in length, which allowed an allocation to each user an address space of 16 MB. Later, the addressability of the architecture was extended to 31 bits, which increased the addressability of virtual storage, and the size of the address space, from 16 MB to 2 GB.
