Key Points
- RAM (Random Access Memory) is primarily composed of semiconductor materials.
- Semiconductor RAM is used to store data temporarily while a computer is running, offering high-speed data access.
- Two main types of semiconductor RAM are DRAM (Dynamic RAM) and SRAM (Static RAM).
- DRAM uses capacitors and requires periodic refreshing to maintain data, while SRAM uses flip-flop circuits and does not need refreshing.
- Semiconductor RAM is known for its volatility, meaning it loses stored information when power is turned off.
Additional Information
- Transistors
- Transistors are used in the construction of RAM cells to store bits of information.
- They act as electronic switches that can turn on or off to represent data as binary 0s and 1s.
- Memory Hierarchy
- RAM is part of the memory hierarchy in computing, positioned between the CPU and storage devices like HDDs and SSDs.
- It provides faster access to data compared to secondary storage devices.
- Non-Volatile Memory
- In contrast to RAM, non-volatile memory like ROM (Read-Only Memory) retains data even when power is switched off.
- Non-volatile memory is used for firmware and other permanent data storage.
- Cache Memory
- Cache memory is a small-sized type of volatile memory that provides high-speed data access to the CPU.
- It stores frequently accessed data and instructions to speed up processing.
