Issues Related to Cache Memory



  • Load-ThroughWhen the CPU needs to read a word from the memory, the block containing the word is brought from MM to CM, while at the same time the word is forwarded to the CPU.
  • Store-ThroughIf store-through is used, a word to be stored from CPU to memory is written to both CM (if the word is in there) and MM. By doing so, a CM block to be replaced can be overwritten by an in-coming block without being saved to MM.
