Similarities between RAM and ROM
In this article, we will discuss the overview of RAM and ROM, and then we will cover different types of each and then mainly focus will be on similarities between RAM and ROM. Let’s discuss it one by one.
Random-access memory(RAM) :
Random-access memory is a type of memory namely volatile memory that is used to store programs and data being used by the CPU. Volatile memory requires power to maintain its stored data or information. The ram is a hardware element in a computer that is installed on the motherboard. And it doesn’t store the whole data present in the computer was as it only stores the data that is currently used by the CPU.

Types of RAM :
RAM is classified into two types as follows.
- Static RAM –
The static ram stores data with the help of a transistor cell.
- Dynamic RAM –
The dynamic ram stores data with the help of both transistor and capacitor cells.
Read-Only memory(ROM) :
Read-Only memory is a type of memory namely Non-volatile memory that is used to store the data in it. And the advantage of Read-Only memory is it can retain the data which is stored in it previously even after turn off the power supply to it.
Types of ROM :
ROM is classified as the following types as follows.
- Erasable Programmable ROM –
This type of ROM is a kind of where the data present in it gets erased when it is exposed to high-intensity UV light.
- Electrically Erasable Programmable ROM –
This type of ROM is a kind of where the data present in it gets erased when it is subjected to field electron emission.
- Mask ROM –
The data present in this type of ROM is written while it’s manufacturing.
- Programmable ROM –
The data present in this type of ROM is written after manufacturing of the ROM.
Similarities between RAM and ROM :
Here are the similarities between both the RAM and ROM as follows.
|RAM and ROM|
|1.||Holds information||Random Access Memory (RAM) and Read-Only Memory (ROM) are the types of Primary Storage devices which hold or store information in the form of program instructions for certain data and also as data that can be directly passed to the computer’s Central Processing Unit (CPU) and INPUT/OUTPUT (I/O) controllers and circuitry of the processor.|
|2.||Accessing memory||Both of these types of Primary Storage can be accessible in this way, they both utilize a type of address bus register to identify the specific memory cell or a group of cells which can be accessed at any given interval of time and data line and bus to carry the information being read from the memory of the device.|
|3.||Binary form||Both of these types of memory devices represent the information present in them as a series of Binary Digits which are also called as (bits) which through either the presence of a voltage represents as (a logical 1 value) or the absence of that same voltage represents as (a logical 0 value).|
|4.||Types||Both RAM and ROM are available in several subcategories and each the types will have different benefits and drawbacks and usage requirements which basically depends on their type.|
We have covered the overview of RAM and ROM and you will be able to understand the similarities one can notice when comparing both RAM and ROM.
