Types of ram for pc and Mobile

Almost all devices with computing capacity need RAM. Take a look at your favorite device (for example, smartphones, tablets, desktops, laptops, graphic calculators, high definition televisions, portable gaming systems, etc.), and you should find information about RAM. Although all RAM basically serves the same purpose, there are a few different types that are commonly used today:

Static RAM (SRAM)
Dynamic RAM (DRAM)
Synchronous Dynamic RAM (SDRAM)
Synchronous dynamic single data rate RAM (SDR SDRAM)
Synchronous dynamic double speed data RAM (DDR SDRAM, DDR2, DDR3, DDR4)
Dual-speed dynamic synchronous RAM data graphics (GDDR SDRAM, GDDR2, GDDR3, GDDR4, GDDR5)
Flash memory
What is RAM?
RAM means random access memory, and gives computers the virtual space needed to manage information and solve problems at the moment. You can think of it as a reusable paper to write on which you would write notes, numbers or drawings with a pencil. If you run out of paper space, you earn more by erasing what you no longer need; RAM behaves similarly when it needs more space to handle temporary information (that is, run software / programs). Larger pieces of paper allow you to scribble more (and more) ideas at once before having to erase them; More RAM inside computers shares a similar effect.

RAM comes in a variety of ways (that is, the way it is physically connected or connected to computer systems), capabilities (measured in MB or GB), speeds (measured in MHz or GHz) and architectures. It is important to take these and other aspects into account when upgrading systems with RAM, since computer systems (for example, hardware, motherboards) must comply with strict compatibility guidelines. For example:

Computers of previous generations are unlikely to support the latest types of RAM technology
Laptop memory does not fit on desktop computers (and vice versa)
RAM is not always compatible with previous versions
A system generally cannot mix and match different types / generations of RAM together
Static RAM (SRAM)
Time in the market: from 1990 to the present
Popular products that use SRAM: digital cameras, routers, printers, LCD screens
One of the two basic types of memory (the other is DRAM), SRAM requires a constant flow of energy to function. Due to the continuous power, it is not necessary to “update” the SRAM to remember the data that is stored. This is why SRAM is called “static”: no change or action is needed (for example, update) to keep the data intact. However, SRAM is a volatile memory, which means that all data that had been stored is lost once the power is cut.

The advantages of using SRAM (vs. DRAM) are lower energy consumption and faster access speeds. The disadvantages of using SRAM (versus DRAM) are lower memory capacities and higher manufacturing costs. Due to these characteristics, SRAM is typically used in:

CPU cache (for example, L1, L2, L3)
Hard disk buffer / cache
Digital to analog converters (DAC) on video cards
Dynamic RAM (DRAM)
Time in the market: 1970 in the mid-1990s
Popular products that use DRAM: video game consoles, network hardware
One of the two basic types of memory (the other is SRAM), DRAM requires a periodic “update” of power to function. Capacitors that store data in DRAM gradually discharge energy; Without energy means that data is lost. That is why DRAM is called “dynamic”: constant changes or actions (for example, updating) are needed to keep the data intact. DRAM is also a volatile memory, which means that all stored data is lost once the power is cut.

The advantages of using DRAM (versus SRAM) are lower manufacturing costs and higher memory capacities. The disadvantages of using DRAM (vs. SRAM) are slower access speeds and higher power consumption. Due to these characteristics, DRAM is typically used in:

System memory
Video memory
In the 1990s, Extended Data Out Dynamic RAM (EDO DRAM) was developed, followed by its evolution, Burst EDO RAM (BEDO DRAM). These types of memory were attractive due to higher performance / efficiency at lower costs. However, the technology was obsolete by the development of SDRAM.

Synchronous Dynamic RAM (SDRAM)
Time in the market: 1993 to the present
Popular products that use SDRAM: computer memory, video game consoles

SDRAM is a classification of DRAM that works in synchronization with the CPU clock, which means that it waits for the clock signal before responding to data input (for example, the user interface). On the contrary, DRAM is asynchronous, which means that it responds immediately to data entry. But the benefit of synchronous operation is that a CPU can process overlapping instructions in parallel, also known as “channeling,” the ability to receive (read) a new instruction before the previous instruction has been completely resolved (write).

Although channeling does not affect the time it takes to process instructions, it does allow more instructions to be completed simultaneously. The processing of a read instruction and a write instruction per clock cycle results in higher overall CPU performance / transfer rates. SDRAM supports channeling due to the way its memory is divided into separate banks, which is what led to its widespread preference over basic DRAM.

Synchronous dynamic single data rate RAM (SDR SDRAM)
Time in the market: 1993 to the present

SDR SDRAM is the extended term for SDRAM: the two types are one and the same, but more often it is known as SDRAM. The “single data rate” indicates how the memory processes a read and write instruction per clock cycle. This labeling helps clarify the comparisons between SDR SDRAM and DDR SDRAM:

DDR SDRAM is essentially the second generation development of SDR SDRAM
Synchronous dynamic double data rate RAM (DDR SDRAM)
Market time: 2000 to the present
Popular products that use DDR SDRAM: computer memory
DDR SDRAM works as SDR SDRAM, only twice as fast. DDR SDRAM is able to process two read and two write instructions per clock cycle (hence the “double”). Although its function is similar, DDR SDRAM has physical differences (184 pins and a single notch in the connector) versus SDR SDRAM (168 pins and two notches in the connector). DDR SDRAM also operates at a lower standard voltage (2.5 V from 3.3 V), avoiding compatibility with SDR SDRAM.

DDR2 SDRAM is the evolutionary update to DDR SDRAM. While it still doubles the data rate (it processes two read and two write instructions per clock cycle), the DDR2 SDRAM is faster because it can operate at higher clock speeds. Standard DDR memory modules (not overclocked) have a maximum of 200 MHz, while standard DDR2 memory modules have a maximum of 533 MHz. DDR2 SDRAM operates at a lower voltage (1.8 V) with more pins (240) , which prevents compatibility with previous versions.
DDR3 SDRAM improves performance over DDR2 SDRAM through advanced signal processing (reliability), higher memory capacity, lower power consumption (1.5 V) and higher standard clock speeds (up to 800 MHz). Although DDR3 SDRAM shares the same number of pins as DDR2 SDRAM (240), all other aspects avoid compatibility with previous versions.
DDR4 SDRAM improves performance over DDR3 SDRAM through more advanced signal processing (reliability), even greater memory capacity, even lower power consumption (1.2 V) and higher standard clock speeds (up to 1600 MHz) . DDR4 SDRAM uses a 288-pin configuration, which also prevents compatibility with previous versions.


Synchronous dynamic dual-speed graphics data RAM (GDDR SDRAM)
Time in the market: 2003 to the present
Popular products that use GDDR SDRAM: video graphics cards, some tablets


GDDR SDRAM is a type of DDR SDRAM that is specifically designed for the representation of video graphics, usually together with a dedicated GPU (graphics processing unit) on a video card. It is known that modern PC games exceed the limits with incredibly realistic high definition environments, which often require strong system specifications and the best video card hardware to play (especially when using high resolution 720p or 1080p screens ).

Like DDR SDRAM, GDDR SDRAM has its own evolutionary line (improves performance and reduces energy consumption): GDDR2 SDRAM, GDDR3 SDRAM, GDDR4 SDRAM and GDDR5 SDRAM.
Despite sharing very similar features with DDR SDRAM, GDDR SDRAM is not exactly the same. There are notable differences with the way GDDR SDRAM operates, particularly with regard to how bandwidth is favored over latency. GDDR SDRAM is expected to process massive amounts of data (bandwidth), but not necessarily at the fastest speeds (latency); Think of a 16-lane road set at 55 MPH. Comparatively, DDR SDRAM is expected to have a low latency to respond immediately to the CPU; Think of a 2-lane road set at 85 MPH.

Flash memory
Time in the market: 1984 to the present
Popular products that use flash memory: digital cameras, smartphones / tablets, portable gaming systems / toys
Flash memory is a type of non-volatile storage medium that retains all data after the power is cut. Despite the name, the flash memory is closer in shape and operation (ie, storage and data transfer) to solid state drives than the types of RAM mentioned above. Flash memory is most commonly used in:

USB flash drives
Printers
Portable media players
Memory cards
Small electronics/toys
PDAs
