Study Notes
Types of Memory
- RAM (Random Access Memory) is the primary type of memory used for data and program code required by computer processors.
- DRAM (Dynamic Random Access Memory) is commonly utilized in personal computers, workstations, and servers, functioning as the main memory.
Advantages of RAM
- The key advantage of RAM over storage media like hard disk drives (HDDs) and solid-state drives (SSDs) is speed; RAM allows for much faster data access and retrieval.
- Unlike HDDs and SSDs, RAM enables high-speed data access and processing, enhancing overall system performance.
Storage of Data in DRAM
- Data in a DRAM storage cell is stored using capacitance; each cell consists of a capacitor and a transistor, which represent binary bits (0s and 1s).
- The stored charge in the capacitor reflects a bit of data, but this charge needs to be refreshed periodically due to leakage.
Random Access
- Random access capability allows the PC processor to read or write data from any memory address directly and at high speed, rather than sequentially.
- This enhances the efficiency and speed of data processing, making it crucial for optimal computer performance.
