What are the main types of RAM?

What are the main types of RAM?

There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM).

  • DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory. …
  • SRAM (pronounced ES-RAM) is made up of four to six transistors.

What are the 4 RAM types?

Although all RAM basically serves the same purpose, there are a few different types commonly in use today:

  • Static RAM (SRAM)
  • Dynamic RAM (DRAM)
  • Synchronous Dynamic RAM (SDRAM)
  • Single Data Rate Synchronous Dynamic RAM (SDR SDRAM)
  • Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4)

What are the 5 features of RAM?

Characteristic of Static RAM

  • Long life.
  • No need to refresh.
  • Faster.
  • Used as cache memory.
  • Large size.
  • Expensive.
  • High power consumption.

What are the types of RAM Class 5?

A5. RAM has two types as follows: SRAM (Static Random Access Memory) DRAM (Dynamic Random Access Memory)

What are SRAM and DRAM?

SRAM (static RAM) is a type of random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which must be continuously refreshed, SRAM does not have this requirement, resulting in better performance and lower power usage.

What is ddr1 DDR2 DDR3 DDR4?

DDR operates are about 2.5 V and DDR2 averages about 1.8 V, with DDR3 the voltage is reduced to 1.5 V. DDR3 has transfer rates between 800MT/s and 1600MT/s.

What are three RAM types?

Integrated RAM chips are available in two form: SRAM(Static RAM) DRAM(Dynamic RAM)…There are mainly 5 types of DRAM:

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

What are types of RAM and ROM?

The two main types of RAM are static RAM and dynamic RAM. The types of ROM include PROM, EPROM and EEPROM.

What is a DIMM?

DIMM (dual in-line memory module) is a type of computer memory that is natively 64 bits, enabling fast data transfer. DIMM is a module that contains one or several random access memory (RAM) chips on a small circuit board with pins that connect it to the computer motherboard.

What are types of ROM?

Let us now discuss the various types of ROMs and their characteristics.

  • MROM (Masked ROM) …
  • PROM (Programmable Read Only Memory) …
  • EPROM (Erasable and Programmable Read Only Memory) …
  • EEPROM (Electrically Erasable and Programmable Read Only Memory) …

What is RAM in computer for Class 5?

It is compact, lightweight and has a storage capacity ranging from 16 MB to 64 GB. f. (i) RAM: The RAM stores the data on which the CPU is currently working. Information can be read from and written on to the RAM.

What is laptop RAM called?

System memory, frequently called main memory or RAM (Random Access Memory), is a type of computer memory that can be accessed randomly.

What is the RAM of a computer?

RAM stands for random-access memory, but what does that mean? Your computer RAM is essentially short term memory where data is stored as the processor needs it. This isn’t to be confused with long-term data that’s stored on your hard drive, which stays there even when your computer is turned off.

Which is better DRAM or SDRAM?

SRAM is faster and typically used for cache, DRAM is less expensive and has a higher density and has a primary use as main processor memory. SDRAM stands for Synchronous Dynamic Random Access Memory, a type of DRAM that is synchronized with the processor system bus for a speed advantage.

Is cache a SRAM or DRAM?

The name of the actual hardware that is used for cache memory is high-speed static random access memory (SRAM). The name of the hardware that is used in a computer’s main memory is dynamic random access memory (DRAM).


RAM is fast but it is volatile, which means it will not retain data if there is no power. It is therefore important to save data to the storage device before the system is turned off. There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM)….ROM and RAM.
