Study Notes
Memory Hierarchy
- The highest level in the memory hierarchy is Cache memory.
Memory Access Methods
- Sequential access allows access in order, retrieving data one after the other.
- Direct access uses unique addresses for each memory location, allowing direct access to any location.
- Content-addressable memory retrieves data based on its content, not its address.
Memory Types
- Random access memory (RAM) is a type of volatile memory that can be accessed randomly.
- Secondary memory is a type of non-volatile storage medium that is used to store data persistently.
Memory System Cost Optimization
- Memory hierarchy aims to optimize the total cost of the memory system by utilizing different memory types with varying access speeds and storage capacities. This involves using a faster but smaller cache memory to hold frequently accessed data, while slower and larger primary and secondary memories hold less frequently used data.
Data Storage Method
- Magnetic Disk is a common type of secondary memory that stores data on tracks with separate read/write heads.
