Hello guys, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between RAM and ROM. There are 2 basic types of memory first one is ROM and the second one is RAM. RAM is volatile memory which means storing data when power is provided to the computer. ROM is a non-volatile memory that retains data when there is no power given to the computer.
In today’s post we will have a detailed look at both ROM and RAM memory with the detailed and find their different parameters. So let’s get started with the Difference Between RAM and ROM.
Difference Between RAM and ROM
RAM
- RAM stands for random access memory it is volatile memory means lost information when there is no power at the computer.
- It is a type of memory unit that stores data and reads and is normally used for storing data.
- Dara can be read and write on it.
- It comprises of multiplex and demultiplexer circuits that help to make the connection between reading and writing.
- It is an eight and sixteen-bit data device generally single address of a bit can be added through it
- It comes in ICs form having MOS memory units.
- Random-access memory permits the computer to read the information very fast.
- RAM performs both read and write functions.
- Its operating speed is fast.
- It is a temporary data storage memory.
- Its price is high.
- Its types are SRAM and DRAM.
- The physical dimensions of RAM are larger than the ROM.
- Its shape is like a rectangle and is inserted into the motherboard of a compute
- It is volatile of nature and stores data till supply is given to it.
- It comes with two main types random access memory and static random access memory.
- Its memory capacity is one to two fifth six gigabytes per chip.
- If power is cut off due to some reason the stored data will be lost in the RAM.
- To get data from the RAM processor get direct access to the RAM..
- It is also known as primary memory.
ROM
- ROM stands for read-only memory. It is a non-volatile memory.
- It stores data on a permanent basis and is employed for storing of different software.
- Normally used video games are stored on ROM
- It comes with the ics having a dot matrix configuration.
- Its memory capacity is four to eight MB per chip.
- It is a read type of memory.
- Its operating speed is less than the RAM.
- Its types are PROM, EPROM, and EEPROM.
- It is a permanent type of memory storage.
- It also called secondary memory.
- It disconnection of power the data still stored in the ROM.
- There is no direct access of the processor to the ROM.
- Its price is less than the RAM.
RAM vs ROM
RAM | ROM |
---|---|
Its full form is Random Access Memory | Its full form is Read-Only Memory |
It is a volatile memory | It is a non-volatile memory |
temporary data storage and program instruction | It permanently stores data |
High-speed read and write | Slow-speed reading and writing |
Many times data can be read | It read many one time but write one time |
SRAM and DRAM main types | PROM, EPROM, and EEPROM main types |
It needed constant power | It does not need any constant power |
I accessed randomly | accessed in a sequenced |
I smaller storage capacity than the ROM | larger storage capacity |
main memory in computers mobile phones etc | firmware boot loaders use |
used for caching frequently accessed data to high-speed access | data storage that needed access frequently or for longer-duration storage |
dynamically used through an operation system | It cannot be dynamically allocated and needs memory space |
it is costly | It is less expensive |
upgraded and replaced in the computer | it can not be upgraded or replace |
It can be accessed through the CPU | accessed by the CPU for reading operations |
it can be shared between different programs and processes | shared between programs and processes |
modern computers have it | it is used in embedded systems |
Features of RAM
- These are some features of RAM.
- RAM is used to start and loading of the operating system of a computer.
- Its speed is high for reading and writing data
- RAM retains till teh supply is on
- In RAM, data stored in GB
- The thirty-two-bit personal computer has four gigabytes of RAM and the sixty-four-bit personal computer has sixteen exabytes of random access memory.
Types of RAM
- These are some types of random access memory.
- DRAM stands for dynamic random access memory.
- SRAM stands for static random access memory
- SDRAM stands for synchronous dynamic random access memory operating with very high speed.
Advantage of RAM
- These are some advantages of RAM.
- it does not have any moving parts and works as the noise-less
- power of RAM is less than the disk drive.
Features of ROM
- These are some features of Read-only memory.
- In ROM only one time data can be written, after writing we can read data numerous times.
- Read-only memory is used in the starting function of modern computers.
- ROM can store four megabytes of data or more.
Types of ROM
- These are some types of ROM.
- EPROM stands for erasable programmable read-only memory,
- PROM stands for programmable read-only memory.
- EEPROM stands for electrically erasable programmable read-only memory.
- MROM stands for MASK ROM is a category of read-only memory The data on this ROM can be written by the ICs creators.
