In this article, you going to see discussion regarding Difference between RAM and ROM in a details and a step by step.
If you are looking for this topic then you are at a right place.
Let’s start with the topic of difference between RAM and ROM.
What is RAM and ROM full form?
RAM full form is Random Access Memory.
ROM full form is Read Only Memory.
These are the two types of memory one which is called Random Access Memory (RAM) and another one is called Read-Only Memory (ROM).
Both are forms of computer memory are used for Storing purposes.
Now you going to see important points regarding RAM, ROM and their comparison.
The CPU in a rel time using RAM for storing data and programs.
Many number times the data get read, write and erased with the help of RAM.
It is a one type of hardware element in which the data is being stored.
RAM is also called as volatile memory.
What are the types of RAM?
Below is given the types of RAM.
First one is Static RAM(SRAM) is used to store bit data with the help of state of six transistor memory cell.
Second one is Dynamic RAM(DRAM) is used to store bit data with the help of pair of transistor memory cell and also capacitor.
Next point is you going to see discussion regarding ROM.
ROM is a unique and best type of memory you can say where the data has been pre-recorded.
This recorded is remain as even if the system is turn off.
Therefore it is also called non-volatile.
What are the types of ROM?
The first one is Programmable ROM in which data get written, it is going to take place only after the memory chip is created and also called non-volatile.
Second one is Erasable Programmable ROM in which data with the help high intensity UV light data is get erase.
The third one is Electrically Erasable Programmable ROM in which data get erase electrically with the help of field electron emission.
Last one is Mask ROM in which data get written during the production of memory chip.
Is cache memory RAM or ROM?
Cache memory is one of the type of RAM.
It is fast and expensive.
Mainly small in size and they can’t retain data without power supply.
What is the difference between RAM and ROM?
| Point on Discuss | RAM | ROM |
| Data recollection | As long as power is supplied data can be store as it is a volatile memory. | Data get remain even when power is turn-off as it is a non-volatile memory. |
| Process of Working | In the RAM, the data which is stored can be retrieved and changed. | In the case of ROM, the data is only read. |
| Use | Use to store data and programs in rel time of CPU | It stores instruction which helps during the process of bootstrap of the computer. |
| Memory Speed | High-speed memory | Slower as compared to RAM. |
| It’s Capacity and Size | Big in Size and More in Capacity | Small in Size and Less in Capacity |
| Used By | CPU Cache, Primary memory. | Firmware, Micro-controllers |
| Point of Accessibility | Easily accessible Stored Data. | Not Easily accessible Stored Data |
| Cost | Expensive | Cheaper as compared to RAM. |
