Study Notes
Memory Types and Characteristics
- Cache Memory: Communicates directly within the CPU and is used for high-speed data access to enhance processing efficiency.
- Auxiliary Memory: Refers to external storage devices like hard drives or SSDs and is not directly accessed by the CPU.
- Main Memory: The primary memory component of a computer system, also known as RAM (Random Access Memory), where active programs and data reside.
Active Memory Usage
- RAM (Main Memory): Used to keep programs or data when the processor is active, allowing for quick read and write access.
- Instruction and Data Storage: In a computer system, RAM is the memory type storing instructions or data for active processor use.
Addressing and Capacity
- 64k Words Memory Address Range: A computer memory with 64k words has an address range from 0 to 65535.
- 128k Words Total Locations: A computer memory with 128k words has a total of 128,000 locations or cells.
- 256k Words Address Range: A computer memory with 256k words has an address range from 0 to 262143.
Memory Refresh and Data Integrity
- Dynamic RAM (DRAM): Characterized by the need for constant refreshing to maintain data integrity, unlike static RAM (SRAM), which does not require refreshing.
Non-volatile Memory
- Non-volatile Memory: Refers to memory types such as ROM (Read-Only Memory) and flash memory, which retain their data even when the power is turned off.
