What is the Difference Between Volatile and Nonvolatile?
🆚 Go to Comparative Table 🆚The main difference between volatile and non-volatile memory lies in their ability to retain data when power is lost or turned off. Volatile memory stores data temporarily and loses it when the power is removed, while non-volatile memory stores data permanently and retains it even when the power is lost or turned off. Here are some key differences between volatile and non-volatile memory:
- Data Retention: Volatile memory loses data when power is lost or turned off, while non-volatile memory retains data even when power is lost or turned off.
- Speed: Volatile memory is generally faster than non-volatile memory. It is used for temporary storage and has faster read and write speeds. On the other hand, non-volatile memory has slower read and write speeds compared to volatile memory.
- Capacity: Non-volatile memory has a larger capacity compared to volatile memory.
- Cost: Volatile memory is generally more expensive per unit size compared to non-volatile memory.
- Power Consumption: Volatile memory requires a constant power supply to maintain data, while non-volatile memory does not require power to retain data.
- Types of Data Stored: Volatile memory stores data from programs that the CPU is processing in real-time and frequently-used information. Non-volatile memory stores data that needs to be saved permanently, such as the operating system, applications, user files, and other permanent data.
- Examples: RAM (Random Access Memory) is a common example of volatile memory, while ROM, EPROM, and EEPROM are examples of non-volatile memory.

Comparative Table: Volatile vs Nonvolatile
Here is a table comparing the differences between volatile and non-volatile memory:
Feature | Volatile Memory | Non-Volatile Memory |
---|---|---|
Data Retention | Data is lost when power is removed | Data remains stored even when power is removed |
Type of Memory | Temporary | Permanent |
Speed | Faster | Slower |
Cost | More expensive per unit size | Less expensive per unit size |
Power Consumption | Requires constant power supply to maintain data | Does not require power to retain data |
Examples | RAM (Random Access Memory) | ROM, EPROM, EEPROM |
Volatile memory is used for temporary storage and loses its data when the power is removed, while non-volatile memory is used for permanent or long-term storage and preserves data even when the power is lost or turned off.
