TextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbook

Answer

Memory interleaving is classified into two types:

  • High Order Interleaving 
  • Low Order Interleaving 

In high-order interleaving, the most significant bits of the address select the memory chip.

In low-order interleaving, the least significant bits  select the memory bank (module).

Differences Between High Order Interleaving And Low Order Interleaving :

Physical memory usually consists of more than one RAM chip. With low-order interleaving, the low order bits of the address specify which memory bank contains the address of interest. Accordingly, in high-order interleaving, the high order address bits specify the memory bank.
