RAM vs ROM: Static RAM vs Dynamic RAM Explained

This page covers the difference between RAM and ROM. It also covers the difference between static RAM and Dynamic RAM. Memories are of two types: primary and secondary.

RAM and ROM are types of primary memory.

Semi-random and serial access are types of secondary memory. Examples of semi-random memories include all disc memories such as CDs, DVDs, etc.

Examples of serial access memories include magnetic tape, magnetic bubble ferrite core, CCD, etc.

RAM vs. ROM

Feature	RAM (Random Access Memory)	ROM (Read-Only Memory)
Access	Read/Write memory	Read-only memory
Volatility	Volatile memory (used for temporary data storage)	Non-volatile memory (used for permanent data storage)
Purpose	Stores data and instructions currently being used by the CPU	Stores boot instructions and firmware

Static RAM vs. Dynamic RAM

Feature	Static RAM (SRAM)	Dynamic RAM (DRAM)
Data Storage	Data is stored like a flip-flop (FF)	Data is stored in a MOS capacitor
Transistor Type	BJT, MOSFET is used	MOSFET is used
Speed	Faster operation	Slower operation
Power Dissipation	Higher power dissipation	Lower power dissipation
Density	Lower density	Higher density
Usage	Used as cache memory	Used as main memory
Refreshing	No refreshing needed	Refreshing is needed
