What Is Memory Dram?
DRAM stands for “dynamic random access memory,” and it’s a specific type of RAM (random access memory). All computers have RAM, and DRAM is one kind of RAM we see in modern desktops and laptops. DRAM was invented in 1968 by Robert Dennard and put to market by Intel® in the ‘70s.
Benefits of Memory Dram
Fast speed: One major benefit to using DRAM is that it offers faster speeds than other types of RAM. This means that your computer will be able to process data much more quickly than if you were using a slower type of RAM.
This speed advantage makes it ideal for applications such as gaming, video editing, and 3D rendering where speed is essential.
Higher density: It has high density, meaning that more bits can be stored in less space than with other kinds of RAM. This helps keep device sizes down since there’s less need for physical space to store the same amount of data compared to SRAM or ROM.
This makes it an attractive option for mobile devices like smartphones and tablets which require small form factors but still need enough memory to support their operations.
Affordable: DRAM is relatively inexpensive compared to other forms of RAM which helps keep overall costs down for consumers when purchasing new equipment or upgrading an existing system.
The low cost also allows device manufacturers to include larger amounts of memory without significantly increasing the price tag for their products.
Low power consumption: Another great benefit of using DRAM is its low power consumption because fewer transistors are needed to operate compared to other forms of RAM like SRAM or ROM.
Types of Memory Dram
SDRAM
The full form of SDRAM is Synchronous Dynamic Random Access Memory. It works according to the clock synchronization, and it synchronizes with the bus, which is present in CPU of the system. It is faster than the DRAM.
RDRAM
The full form of RDRAM is Ram bus Dynamic Random Access Memory. As the name implies, it developed by Rambuys Inc. its operating speed is more as compared to the other types of DRAM.
Asynchronous DRAM
As its name implies, asynchronous DRAM does not work according to the synchronization of the clock. Here, the system contains a memory controller and this memory controller synchronized with the clock. Due to which, the speed of the system is also slow.
FPM DRAM
FPM DRAM stands for Fast Page Mode Dynamic Random Access Memory. Nowadays it is out of date as it can only support memory bus speeds up to 66MHz, but designed for the faster version.
EDO DRAM
EDO DRAM stands for Extended Data Out Dynamic Random Access Memory. It designed so that it can provide faster performance and low cost as compared to FPM DRAM.
BEDO DRAM
BEDO DRAM stands for Burst EDO DRAM. The benefit of BEDO DRAM over EDO DRAM is that it can process four memory addresses in one burst or you can say that it saves three clock cycles. BEDO DRAM usage is very less because when it introduced in the market, at that time another memory SDRAM is also launched and it took the market.
DDR SDRAM
Double Data Rate SDRAM (DDR SDRAM) performs double-width access internally at the clock rate and adopts a double data rate interface to transfer one half on each clock edge. It has had different iterations as time goes on, including DDR2 SDRAM, DDR3 SDRAM, and DDR4 SDRAM.
VRAM
Video RAM (VRAM) is used to store frame buffers in some graphics adapters.
A memory cell in DRAM contains a transistor and capacitor and stores a bit. Every memory cell stores a bit of data, and the transistor is responsible for charging the capacitor when a bit must be stored. When the computer is ready to store data, it sends a charge to the transistor. The charge initiates storage of bits, and the memory cell is recharged every few milliseconds to ensure data is not lost. Capacitors slowly lose their charge, so an external refresh circuit rewrites data to the capacitor and refreshes its charge. DRAM has a finite number of bits it can store, but the number of circuits determines the amount of bits DRAM can store. A single DRAM chip usually stores 8GB, 16GB, 32GB, or 64GB.
Computers work with the binary number system, which is a series of ones and zeros. However, when working with memory maintenance and data assignment, DRAM addresses are presented in hexadecimal notation, which is a base-16 number system. A DRAM chip contains an array of memory banks arranged in rows and columns. At the intersection of a row and column is the capacitor containing a bit. When the CPU needs data from DRAM, a control unit retrieves bits and sends them to the CPU. The CPU sends output back to the control unit, which then sends it to DRAM to store for application use.
What Are the Common Types of DIMM?
There are several DIMM architectures. Different platforms can accommodate different memory types so it is best to check which modules are supported on the motherboard. Here are the most common standard DIMMs, with a typical length of 133.35 mm and height of 30 mm.
|
DIMM Type |
Description |
|
Unbuffered DIMMs |
Used mainly on desktop and laptop computers. They run faster and cost less, but are not as stable as registered memory. Commands go directly from the memory controller residing in the CPU to the memory module. |
|
Fully buffered DIMMs |
Typically used as main memory in systems requiring large capacities such as servers and workstations, FB-DIMMs use advanced memory buffer (AMB) chips to increase reliability, maintain signal integrity and improve error detection methods to reduce soft errors. The AMB bus is split into a 14-bit read bus and a 10-bit write bus. By having a dedicated read/write bus, reads and writes can happen simultaneously, resulting in increased performance. Lesser pin counts (69 pins per serial channel compared with 240 pins on parallel channels), result in lesser routing complexity and allowing smaller board designs for compact, small form factor systems. |
|
Registered DIMMs |
Also known as "buffered" memory, are often used in servers and other applications requiring stability and robustness. RDIMMs feature onboard memory registers (hence the name "registered") placed between the memory and memory controller. The memory controller buffers Command, Addressing and Clock Cycling, directing instructions to the dedicated memory registers instead of accessing the DRAM directly. As a result, the instructions could take approximately one CPU cycle longer, but the buffering reduces the strain on the CPU's memory controller. |
|
Load Reduced DIMMs |
Use Isolation Memory Buffer (iMB) technology, which reduces the load on the memory controller by buffering both data and address lanes. Unlike the register on RDIMMs which buffer only Command, Addressing and Clock Cycling, the iMB chip also buffers data signals. The iMB chip isolates all electrical loading including data signals of the DRAM chips on the DIMM from the memory controller, so the memory controller only sees the iMB and not the DRAM chips. The memory buffer then handles all reads and writes to the DRAM chips, boosting both capacity and speed. (Source: Isolation Memory Buffer) |
DRAM vs SRAM
There are two main classifications of primary memory — DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory).
SRAM uses a six-transistor memory cell to store data, as opposed to the transistor and capacitor pair approach taken by DRAM. SRAM is an on-chip memory typically used as cache memory for CPUs. It’s considerably faster and more power efficient than most other types of RAM, including DRAM. However, it is also significantly more expensive to produce and isn’t user-replaceable/ upgradeable. DRAM, on the other hand, is often user replaceable. Here are the key differences between DRAM and SRAM:
|
DRAM |
SRAM |
|
It uses capacitors to store data |
It uses transistors to store data |
|
Capacitors need constant refreshing to retain data |
Doesn’t need refreshing as it doesn’t use capacitors to store data |
|
Has slower speeds than SRAM |
Significantly faster than DRAM |
|
Cheaper to manufacture |
Very expensive |
|
DRAM devices are high-density |
SRAM is low-density |
|
Used as main memory |
Used as cache memory for CPUs |
|
Relatively lower heat output and power consumption than SRAM |
High heat output and power consumption |
How Much RAM Do You Need?
Operating systems, games, and applications, all need a set amount of RAM to run, and even more to run well, so it’s important to make sure you have enough RAM. This is typically between four gigabytes (GB) and 16GB, though any modern PC running Windows shouldn’t really have any less than 8GB. Modern gaming PCs mostly use 16GB, though some modern AAA games can benefit from 32GB. Anyone looking to do a lot of video editing, or heavy multi-tasking might want 32GB or even more.
Having more than the minimum amount of RAM is essential. A PC runs not only the current application but also other services and tasks in the background. However, having massive amounts of system memory doesn’t necessarily make a PC run faster, and once you have enough, it’s better to have faster memory, than simply more of it.
