What is Memory

They are memory areas where various programs are run on the computer or any electronic device, where temporary or permanent information will be found. The Datagram is Byte. A Byte is 8 Bits. Consists of 1 Bit 0 or 1 (closed circuit=0, open circuit=1). 1 BYTE is 1 character. 1024 BYTE = 1 KiloByte. (KiloByte = KB) is 1024 KB = 1 MegaByte. (MegaByte = MB) 1024 MB = 1 GigaByte (GigaByte = GB) 1024 GB = 1 TeraByte (TeraByte = TB) There are two types of memory in-computer, RAM and ROM memory. memory

ROM Memory and Types

ROM is a general expression that is used only for readable memory. The first rom produced is readable only. Then, electrical changes can be made on the ROM types produced. Memory units of this type are used in cases where information should be stored even when the power is out. In general, it is divided into four groups. MPROM(masceble programmable read only memory-mask programmed ROM) is a special program or type of ROM programmed by the manufacturer used to mask data. PROM (programmable read only memory – programmable ROM) It is a type of ROM that can only be programmed once by the user with a special circuit called a ROM programmer. epromEPROM(erasable programmable read only memory- erasable programmable ROM ) It is a type of ROM that can be erased with ultraviolet light and can protect the information in it for years. Ultravione light is supplied through a small window closed with quartz on the protective body. EepromEEPROM/FLASH ROM (erasable programmable read only memory- erasable programmable ROM ) It is a type of ROM that can be electrically modified, deleted, and reloaded while in operation.

What is RAM?

RAM (Random Access Memory) is a type of data storage format used in microprocessor systems. Random Access Memory in Turkish is the memory where all the information and transactions used in the operating system and our computer are temporarily stored. RAM needs a continuous flow of electricity to maintain its contents. Because it is temporary, it also protects the information in it as long as the computer is running. If the computer shuts down, all information in this memory is deleted. "Whatdoes RAM do?" is used for temporary storage of data and programs to be processed on the computer. memory

RAM History

Before RAM memory was developed, computers, relays and different vacuum tube arrangements were used to implement hundreds of thousands of bits of master memory functions. Systems made with vacuum tubes and transistors have been continuously improved for smaller and faster memory. It wasn't like failures weren't happening. Ram memory was created using semiconductor diode matrices guided by address solvers even before the development of integrated ROM circuits. Ram memory developed between 1949 and 1952 was used as magnetic core memory from the early 1970s until static and dynamic integrated circuits were developed. Memory used in many areas such as microprocessors, digital signal processing (DSP) circuits, LCD screens, printers,hard drives, digital cameras and mobile phones is mostly used in personal computers.

What are the types of RAM?

RAM memory, which is classified depending on how data is protected, is mainly classified as Static RAM (SRAM) and Dynamic RAM (DRAM). memory

  • DRAMA: This memory uses electrical signals to exchange information and capacitors to host data. Therefore, it needs constant regeneration and is renewed thousands of times in a second, but remains slower than SRAM.
  • SRAM: This memory uses on-off switches (transistors) instead of capacitors to hold information, as in DRAM, and does not require regeneration. Therefore, it is faster and more expensive than DRAM. It can also hold more information.
  • SDRAM: This memory is a type of RAM memory that runs simultaneously with the processor. The change in input is more frequently preferred because it is detected and responded to quickly and keeps the processor waiting less.
  • DDR RAM: The clock signal used in this memory is approximately twice as fast as SDRAM memory. The data transfer rate of 100 Mhz DDR RAM is 1,600 MB/s. These memories are very successful in graphics-heavy operations. They use a 64-bit bus and consume less energy. It is developed as DDR2, DDR3, DDR4, DDR5.
  • DRD RAM: These memory, produced by a company called Rambus, produced high speeds using a 16-bit bus. It is the latest technology used today. It is at 1.6 GB/s.
  • PSRAM: The memory, which offers the benefits of DRAM such as high density and ease of use of SRAM, has a refresh and address control circuit very similar to SRAM. It is used in many embedded systems, such as Apple products.
  • RLDRAM: Applications with a high read-write rate of the type of memory used in networking and caching applications are utilized.
  • SGRAM: It is used in graphics adapters and can open two memory pages at a time. This type of memory, which also offers bit masking and block writing, is specifically designed for high performance acceleration purposes used on video cards.

RAM Memory by Size:

30-pin SIMM Memory: It used to be used on old computers. It was disconsed after the '486s. The number of pins where the RAM memory was connected to the motherboard was quite small and was a small-sized memory. 72 pin SIMM Memory: It's out of production with the Pentium II' The number of teeth attached to the motherboard was 72. 168 pin DIMMBellek: Today's motherboards use these 168-geared memory. This size was used in the EDO and SDRAM memory models. memory SDRAM Memory[/CAPTION]

RAM Memory by Chips on:

Standard RAM Memory: It's off the market, it's out of production. EDO RAM Memory: There were dimm-sized ones. It was 50-60 nanoseconds (ns). These are off the market, they're out of production. SDRAM Memory: entered the market with 10-12 ns. Then, with processors using the 100 MHz bus, pc/100 standard, 6-8 ns. PC/133 is widely used today. RDRAM Memory: Pentium IV motherboards support this type. Ram Memory By Characteristics Parity RAM Memory: When information reaches memory in 0 and 1, an extra chip calculates in binary number pattern, sending the data back and recalculating if the total number is incorrect. Error Fixed (ECC RAM) Memory: When he understands the misinformation, he solves and corrects which 0 and 1 the error is. RAM Memory with SPD: Especially in systems that use the 100 MHz bus, they stop by the chip in memory and ask about the situation and learn the speed and features of the chip. If the motherboard supports this, it mediats with commune RAM using the necessary information.

What should be considered when buying RAM?

Every computer needs RAM memory. Programs that don't require a lot of data space, as well as media editing programs like Adobe Photoshop, require more data space. Games are also the software that requires the most power in terms of memory. memory The greater the amount of RAM on your computer, the more multitasking is allowed, which means running multiple programs. In addition to RAM memory features, the amount of memory for the user can also be adjusted.

  • Although we divided computer users into 4 sections; Those who use the computer only to browse the internet, read e-mail, use Word – Excel, play online games, listen to music and watch movies do not need very high memory. 2 GB of memory will be quite enough.
  • It will also see the needs of 2 – 4 GB of RAM memory for those who play games that are not very high in graphics with photo and video editing.
  • 3D modeling like 3DS Max, 4 – 8 GB of RAM will be good when games like NFS are added.
  • 3D modeling, image and video processing, high graphics games, and professional users using high-spec drawing software use 12 to 16 GB of RAM memory.

Even if there is not much action if there is no financial difficulty, 8 GB or more can be preferred as laptop or desktop memory in terms of processing speed and forward.' In addition, ram memory running at 1066 Mhz or 1866 Mhz can be preferred according to how much your motherboard supports it. The lower the CL value in ram, the faster the memory runs. If you are going to get an attachment to the RAM on your system, they must both have the same Mhz value. You should also pay attention to how many Volts of RAM memory your motherboard supports.
