Memory Hierarchy

• the storage pyramid (access time versus size)
• memory types
  • basic difference between an SRAM and DRAM with their advantages and disadvantages
  • Other derivates based on this basic structures: new memory architectures RDRAM,SDRAM in a principal overview...
• Basic principle of a DRAM function to explain the advantage for fast read-out of complete lines instead of single bytes
• Cache structures
  • direct mapped, fully associative, n-way/set associative
  • effective access times
  • types of locality
  • cache acceleration techniques: bypassing, miss acceleration, write buffers, victim buffers, speculation
