DRAM Full Form in Computer

By Anjnee Bhatnagar|Updated : September 30th, 2022

DRAM full form or DRAM stands for Dynamic Random Access Memory. While learning about the computer components you may have encountered the term RAM which stands for Random Access Memory, what about the DRAM? DRAM has enhanced the functionality of RAM. Here we will check the DRAM full form and other related information.

In this article, we will learn about the DRAM full form in computer, the need for DRAM, and the various types of DRAM available. DRAM is present in all modern desktops and laptops. Invented in the year 1968, DRAM has become a part of all modern-day computers. Let us first discuss the DRAM full form.

What is DRAM Full Form in Computer?

DRAM full form is Dynamic Random Access Memory and is a specific type of RAM. It is a volatile memory that stores data in transistors. It is situated closer to the processor so that access to data and other processes can be performed quickly. RAM uses transistors to store data, transistors need electricity to work, therefore anything you store disappears when you turn off the computer or PC.

Features of DRAM

The Dynamic Random Access Memory (DRAM Full Form) stores data for a short period of time. It needs power or electricity to retain the data. Let us now look at the features of DRAM:

  • The cost of DRAM(DRAM Full Form: Dynamic Random Access Memory) is less than SRAM (SRAM Full Form: Static Random Access Memory).
  • It is used in the manufacturing of large-sized RAM.
  • It has high storage capacity.
  • Its structure is simple and easy to maintain.
  • It is smaller in size in comparison to SRAM.
  • Power consumption is less than SRAM.

Types of DRAM

Due to the use of transistors and capacitors in each cell, DRAM (DRAM Full Form: Dynamic Random Access Memory) is slow. The information stored in the cell can be read correctly if the charge on the capacitors drops below some threshold value. There are majorly five types of DRAM. Following are the types of DRAM:

  • Asynchronous DRAM (ADRAM)
  • Synchronous DRAM (SDRAM)
  • Double Data Rate SDRAM (DDR SDRAM)
  • Rambus DRAM (RDRAM)
  • Cache DRAM (CDRAM)

Advantages of DRAM

The full form of DRAM is Dynamic random access memory. It is a particular kind of RAM (random access memory). Every computer has RAM, and DRAM is one type of RAM that is common in contemporary desktop and laptop computers. Further, let us check the advantages of DRAM.

  • In order to create more RAM for the system, DRAM is used.
  • In comparison to other RAM types, DRAM can store more data per gigabyte.
  • DRAM is significantly less expensive than other forms of memory.
  • DRAM can retrieve data faster.

What is the Difference Between SRAM and DRAM?

Let us have a brief look at what makes SRAM different from DRAM. We have been discussing the DRAM (DRAM Full Form: Dynamic Random Access Memory) throughout the article. SRAM stands for Static Random Access Memory, it stores data in transistors and needs a continuous power supply. The differences between SRAM (SRAM Full Form: Static Random Access Memory) and DRAM are as follows:

SRAM

DRAM

Fast access speed.

Slow access speed.

Does not require a refreshing unit.

Requires refreshing unit.

They are low-density devices.

They are high-density devices.

Used to construct cache memory.

Used to construct main memory.

FAQs on DRAM Full Form

  • DRAM Full Form is Dynamic Random Access Memory. It is a volatile memory that stores data. This memory is positioned nearer to the processor, the computer can access it fast.

  • DRAM stands for Dynamic Random Access Memory, it is a volatile memory that is inexpensive but requires power or electricity for operating for a long time. There are majorly five types of DRAM, they are as follows:

    • Asynchronous DRAM (ADRAM)
    • Synchronous DRAM (SDRAM)
    • Double Data Rate SDRAM (DDR SDRAM)
    • Rambus DRAM(RDRAM)
    • Cache DRAM(CDRAM)
  • RAM stands for Random Access Memory, it is also known as main memory, it is volatile in nature. It is used to store data that is recently processed by the CPU. Integrated RAM chips are available in two types SRAM (SRAM Full Form: Static Random Access Memory)and DRAM (DRAM Full Form: Dynamic Random Access Memory). SRAM stands for static random access memory and DRAM stands for dynamic random access memory.

  • In ADRAM or asynchronous DRAM (DRAM Full Form: Dynamic Random Access Memory), the timing of the memory device is controlled asynchronously. It works on the generated controlled signals and synchronizes with the timing. The CPU takes into account the delay in the response of the memory.

  • The cache memory is a very high-speed memory, it is even faster than the main memory. Cache memory is constructed using SRAM (SRAM Full Form: Static Random Access Memory) which is why it does not need any refreshing unit to keep data intact. On the other hand, the main memory is constructed using DRAM (DRAM Full Form: Dynamic Random Access Memory) which makes it slow working than cache memory and therefore cheaper in cost.

  • SRAM has lower access time than DRAM, SRAM is more expensive than DRAM, and SRAM has less storage capacity than DRAM.
