Types of RAM

What are the Types of RAM?

The following types of RAM are given below.

  • SRAM - Static Random Access Memory
  • DRAM - Dynamic Random Access Memory
  • FPM DRAM - Fast Page Mode Dynamic Random Access Memory
  • EDO DRAM - Extended Data Out Random Access Memory
  • SDRAM - Synchronous Dynamic Random Access Memory
  • DDR SDRAM - Double Data Rate Synchronous Dynamic Random Access Memory
  • RDRAM - Rambus Dynamic Random Access Memory
  • DDR2 - Double Data Rate 2 Synchronous Dynamic Random Access Memory
  • DDR3 - Double Data Rate 3 Synchronous Dynamic Random Access Memory
  • DDR4 - Double Data Rate 4 Synchronous Dynamic Random Access Memory
  • VRAM - Video Random Access Memory

Random Access Memory (RAM)

The Random Access Memory is a volatile memory or temporary storage device and its used to store working data and machine code and Random Access Memory allows data to read or write in the physical location of data in contact with direct access to storage media such as DVD read/write, CD read/write, and hard disk. Therefore it is a part of the computer’s main memory which is directly accessible by CPU and it is volatile in nature, it means if the power goes off, the stored information is lost and it is use to store the data that is currently process by the CPU and most of the programs and data that are modifiable are store in RAM.

SRAM - Static Random Access Memory

Static Random Access Memory(SRAM) is a volatile memory, when power is off data is lost. The term static differentiates SRAM from DRAM which must be periodically refresh. It consists of circuits capable of retaining their state as long as power is on this type of memory is a volatile memories.

DRAM - Dynamic Random Access Memory

Dynamic Random Access Memory (DRAM) is a type of random-access semiconductor memory that stores the binary information into a memory cell of a capacitor that tends to lose over a period of time and therefore the main memory is made up of DRAM chip.

FPM DRAM - Fast Page Mode Dynamic Random Access Memory

Fast Page Mode Dynamic Random Access Memory (FPM DRAM) is a type of Dynamic RAM designed for the fastest access to data in the same row or column and therefore individual bits are store in each cell of the array.
FPM DRAM

EDO DRAM - Extended Data Out Random Access Memory

Extended Data Out Random Access Memory (EDO DRAM) is a type of faster page mode dynamic RAM whose main features were to reduce the time which reads from memory as a faster microprocessor such as Intel Pentium.
EDO DRAM

ADRAM - Asynchronous Dynamic Random Access Memory

Asynchronous Dynamic Random Access Memory (ADRAM) is the older type of DRAM it asynchronously controls the timing of the memory device is also known as first-person computers because memory device timing is not synchronized with the computer system clock and the timing of the memory device is control by the memory control circuits that generate the control signal for controlling time.
ADRAM

SDRAM - Synchronous Dynamic Random Access Memory

Synchronous Dynamic Random Access Memory (SDRAM) is a type of DRAM with an interface synchronous with the system bus which carries data between the central processing unit (CPU) and the memory controller hub and a processor can perform in a given time due to an increase in the number of instructions.
SDRAM

CDRAM - Cache Dynamic Random Access Memory

Cache Dynamic Random Access Memory (CDRAM) is the type of DRAM with an on-chip cache memory is a CDRAM. Therefore it acts as a high-speed buffer for the main memory and it contains 1 MB DRAM and 8 KB static RAM for cache memory.
CDRAM

DDR SDRAM - Double Data Rate Synchronous Dynamic Random Access Memory

Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM) is the fastest version of SDRAM and is the class of integrated circuits used in computers. Therefore the data transfer rate was double by transferring data on both edges of the clock and it improves memory access speed up to 200 MHz.
DDR SDRAM

RDRAM - Rambus Dynamic Random Access Memory

Rambus Dynamic Random Access Memory (RDRAM) is the type of SDRAM developed by Rambus. It provides a very high data transfer rate over a CPU memory bus. The various speedup mechanisms are very fast signal timing, cache inside the DRAM chips, and synchronous memory interface. The size of the Rambus data bus is 8 to 9 bits width.

DDR2 SDRAM - Double Data Rate 2 Synchronous Dynamic Random Access Memory

Double Data Rate 2 Synchronous Dynamic Random Access Memory (DDR2 SDRAM) is a high-performance SDRAM interface and is the second generation of double data rate SDRAM and its performance is increased significantly. Due to a wide array of capabilities, it makes DDR2 an excellent memory.
DDR2 SDRAM

DDR3 SDRAM - Double Data Rate 3 Synchronous Dynamic Random Access Memory

Data Rate 3 Synchronous Dynamic Random Access Memory (DDR3 SDRAM) is a type of Synchronous Dynamic Random Access Memory with a high bandwidth interface and it is the high-speed successor DDR to DDR2 SDRAM chips and it has different signaling voltages, timing, and other factors were DDR3 SDRAM is neither forward nor backward compatible with any type of random access memory.
DDR3 SDRAM

DDR4 SDRAM- Double Data Rate 4 Synchronous Dynamic Random Access Memory

Double Data Rate 4 Synchronous Dynamic Random Access Memory (DDR4 RAM) is a class of memory integrates circuits used in computers and it is the type of random access memory module that allows faster transfer rate and higher performance compare to early RAM modules and it transfers memory both the edges rising and falling of a clock, it doubles the transferred data rate.
DDR4 SDRAM

VRAM - Video Random Access Memory

Video Random Access Memory (VRAM) is a high-speed array or dual-ported variant of dynamic RAM which used to store the frame buffer in graphics adapters is also known as simple video memory. For example, image and video data are stores for displays computer.
