Explanation is RAM And ROM Memory

What is a RAM Memory? (Random Access Memory)

Computer Memory, RAM Memory which stands for random access memory, is a sort of Computer Memory that is used for the purpose of temporarily storing data that the computer is now using or processing. RAM And ROM Memory, Random-access memory (RAM), being a type of volatile memory, loses its stored information upon power switching off. The computer commonly uses RAM And ROM Memory, (RAM) to store its operating system, application programs, and current data.

Types of Random Access Memory (RAM)

Static RAM (SRAM) :

The abbreviation for “Static Random Access (SRAM) RAM Memory” is “SRAM.” The production of microprocessors and computer equipment extensively uses this semiconductor.

Dynamic RAM (DRAM) :

The abbreviation for “DRAM” is “Dynamic Random Access Memory.” Its construction uses capacitors, and its data life cycle is shorter than that of static RAM.

What is a ROM Memory? (Random Only Memory)

Computer Memory, ROM Memory, often known as ROM, is a sort of computer memory that is used for the purpose of storing data in a permanent manner that does not need any modifications. A ROM is a kind of memory that is non-volatile, which means that the information that is stored in it is preserved even if electrical power is switched off. ROM is primarily used for the purpose of storing the basic input/output system (BIOS) of a computer. This RAM And ROM Memory system is responsible for storing the instructions necessary to start the computer, in addition to firmware related to other hardware components.

Types of Random Only Memory (ROM)

• PROM (Programmable Read-Only Memory)
• EPROM (Erasable Programmable Read Only Memory)
• EEPROM (Electrically Erasable Programmable Read Only Memory)
• MROM (Mask Read Only Memory)

PROM (Programmable Read-Only Memory) :

Additionally, it can be programmed by the user. Once programmed, the user cannot alter the data and instructions included inside it.

EPROM (Erasable Programmable Read Only Memory) :

It is possible to reprogram it. Put it in the presence of UV light to get rid of the data on it. To re-program it, you must first delete all of the past data.

EEPROM (Electrically Erasable Programmable Read Only Memory) :

We can use an electric field to delete the data, and we don’t need ultraviolet light for this process to succeed. We are able to delete.

MROM (Mask Read Only Memory) :

The term “mask ROM” refers to a kind of read-only memory that is intentionally obscured during the manufacturing process. There is no way for the user to alter the data that is stored in the mask ROM, just as it is not possible with other forms of ROM. If it were possible, the procedure would be challenging or time-consuming.
