Introduction
With everyday tasks, computing has become an essential part of day-to-day life, and knowing how your device allocates memory is important, especially when considering performance. What is DRAM? Why is it a volatile memory? And what is DRAM in SSDs? We will answer all your queries with the help of this guide. If you are in the process of upgrading your system or just curious about its inner workings, rest assured that we will explain everything.
What is DRAM?
Dynamic Random Access Memory, or DRAM, is one of the types of computer memory which is used for keeping data that is currently in use. Unlike SSD and HDD, which are built to permanently store data, DRAM is designed to store short-term information, like cache, while powering on the device. Furthermore, if the device is shut down, the contents within the DRAM will be erased. This is why it is classified as Volatile memory.
DRAM is critical for separate tasks such as gaming or running heavy tasks like software editing and multitasking. Every time you open software, or browse the web page or edit a video, your computer uses DRAM to store your files and access temporary data quickly.
How DRAM Works in a Computer?
A DRAM, or Dynamic Random Access Memory, is made up of multiple capacitors in an integrated circuit, each of which stores a single bit of data. To retain their data, the capacitors are automatically refreshed a thousand times per second. Of course, this is why it’s called dynamic. The refresh cycle is the most distinguishing feature of DRAM when compared to static RAM (SRAM), which does not require refreshing.
To fetch and execute instructions the CPU accesses DRAM constantly. You need to add more DRAM in your system to speed up multiple operations more efficiently without slowing down or relying on slower storage substitutes.
Types of DRAM
It is essential to know what type of DRAM you will purchase when upgrading or building a PC. Below are the common types:
- DDR – Double Data Rate: This is the most common form of DRAM today. We are currently in the era of DDR4 and DDR5.
- SDRAM – Synchronous DRAM: This type of DRAM will synchronize to the system clock and be used in older systems.
- RDRAM – Rambus DRAM: Rambus DRAM is used in specialized systems but largely obsolete now.
- LPDDR – Low Power DDR: Low power DDR commonly used in mobile devices due to power efficiency
Each new generation of DDR DRAM is progressively more efficient than its predecessor in higher speed, bandwidth, and general efficiency.
What is DRAM Memory in SSDs?
Many SSDs come with a DRAM cache to boost speeds. This cache memory helps write speeds and access times by keeping a map of the data stored on the drive.
So, what is DRAM in SSDs? It serves as a spatial data map, similar to how RAM augments data fetching. However, DRAM-less SSDs take a different approach; they use a portion of the system’s RAM, which is slower and may have an impact on overall system performance, particularly during peak workloads.
If you need an SSD for gaming, content creation, or data transfer often, selecting one with DRAM will give you better performance.
DRAM vs. SRAM: What’s the Difference?
DRAM and SRAM are defined as RAM but both work differently and play diverse roles. Let’s find out the difference between both of them:
| Feature | DRAM | SRAM |
| Refresh Needed | Yes (constantly) | No |
| Speed | Slower | Faster |
| Cost | Less expensive | More expensive |
| Usage | Main system memory (RAM) | CPU cache, registers |
| Density | Higher (more data per chip) | Lower |
SRAM is faster and more stable but also bulkier and costlier, that’s why DRAM is the preferred choice for general purpose system memory due to its higher density and cheap prices in the market.
Why is DRAM Called Volatile Memory?
Volatile memory is memory that is lost when the power supply is interrupted. DRAM or Dynamic RAM constantly needs electrical power to sustain the data it holds. Non-volatile memory like solid-state drives (SSD) and hard disk drives (HDD) does not require power to maintain stored information, but DRAM is cleared of its information every shutdown or reboot of your computer.
This is why documents that were not saved suddenly vanish during a sudden power interruption because the information was stored in volatile memory like DRAM.
How DRAM Affects System Performance?
Technology has real-life applications, if your computer contains a higher amount of DRAM, the more tasks it can efficiently execute without dragging or slowing down. If you’re using heavy applications such as Photoshop, video editing applications, or even high-end games, having extra DRAM prevents lag and greatly enhances responsiveness.
DRAM also plays a vital role in SSDs. It decreases write amplification, especially during high-volume data input operations, and it better manages flash memory and other associated components. This improves the SSD’s overall lifespan by reducing unnecessary write operations
Key Factors to Consider When Buying DRAM
When choosing the DRAM for your system or SSD, keep the following key factors in your mind:
- Capacity: 8GB is the standard, while 16GB or more is preferred for advanced users.
- Speed: If the speed of DRAM is higher it has better quality, which is indicated in MHz, such as 3200MHz or 4800MHz. higher is better.
- Latency: Lower CAS latency (CL) leads to quicker data access.
- Form Factor: DIMMs are used for desktop PCs, while SO-DIMMs are used for laptops. Choosing the right DRAM ensures that you get the best value and performance for your computing needs.
- Compatibility: Ensure that the motherboard of your system must be supported by DDR generation.
Picking the proper DRAM guarantees maximized value and five-star performance based on your computing needs.
DRAM Capacity: How Much Do You Need?
If you are looking for DRAM with good capacity then use this recommendation for the estimate criteria:
- 4GB: 4Gb is best for basic web browsing and office work but not recommended for multitasking.
- 8GB: 8GB is suitable for newbie gamers and productivity tasks.
- 16GB: 16 GB capacity widely recommended for most users, including moderate gaming and multitasking.
- 32GB+: Best for professional creators, video editors, and power users.
When considering what DRAM memory is best for your system requirements, always analyse your workflow. More memory in your system means smoother multitasking and future-proofs your setup.
Future of DRAM Technology
Dynamic Random Access Memory (DRAM) has a very bright future. As the adoption of DDR5 increases, users can look forward to improved performance, efficiency, and larger modules. Research is also being done on future generations memory types of DRAM-like speeds that could offer non-volatile characteristics.
