What is RAM and types of RAM

RAM is also known as Random access memory and also known as a real time memory. It is a hardware of computer. people thinks that high storage RAM makes PC faster and low storage makes PC slower. there are other factors too that matters in PC’s speed. The time to access data from the storage unit is dependent on storage unit, it is also called a RAM. random access memory  is directly connected with motherboard.

When we boot up our PC at that time the operating systems load up in the RAM from a storage device like HDD’s and SSD’s and then other applications and software which meant to be  use are load up on the RAM. All types of RAM contains multiplexing and demultiplexing circuits. That connects to the address to the address storage. Sometime RAM have a multiple data lines that is known as “8bit” or “16bit” etc. RAM is a volatile memory. Which stores a data for less period of time. Which means while using your computer the power gets cutoff the whole data will be lost. Which means volatile memory needs constant power. RAM is basically primary memory of the computer or  laptop. It is made up of small IC’s(integrated chips). We can modify the storage of RAM as per the priority. RAM is available in 512MB, 1GB, 2GB ,4GB etc. sometimes heavy users like gamers, GFX artists need high capacity of RAM because it’s software consumes too much space or they do multitasking at a same time. Nowadays a movie editor have at least 128GB of RAM to do editing and VFX work at a same time. Some motherboard have extra slots of RAM so we can expand the storage when we need.

History Of RAM

The first RAM showed in practical form was William’s tube in 1947. It has a capacity around a few hundreds to thousand bits ,but it was a smaller, faster and powerful. This RAM was developed in the university of Manchester in England. The first program which was already stored, implemented in the Manchester baby computer, which successful run a program om 21 June 1948 for the first time.

In 1990s clock speed were synchronized with the introduction of DRAM and SRAM. It synchronize computer’s memory with processor so it executes operation faster. The original single data RAM reached it’s limit too early. After some years double synchronized RAM developed which is works faster than single clock speed RAM .

In early 2005 DDR technologies were developed more. It becomes more powerful and exclusive. At first DDR2, DDR3, DDR3, DDR4 and nowadays DDR6 technologies are spreading around the technologies. each DDR technologies were improved throughput speed and reduced power use but every DDR technologies are incompatible with earlier ones because every data is carried in bigger batches.

Types Of RAM

SRAM (Static Random Access Memory)

SRAM is a modern RAM which is widely used in nowadays in this memory. the data is stored in bit using six-transistor memory cell by using six MOSFETs. this type of RAM is more expensive than DRAM and it is generally faster and require less power than DRAM. In this modern time SRAM is often used as a cache memory for the CPU. Generally SRAM is very easy to understand and similar to flip flop, but the cons of the SRAM is it is a power consumption and heated to early.

 

DRAM (Dynamic Random Access Memory)

DRAM stores the data using transistor and capacitor holds a high or low charge, and the transistor  acts as a switch and let the chip read the capacitors state of charge. DRAM is less expensive than SRAM. DRAM is a main element of computers in the modern time. The mechanism of DRAM is quite complex. It is same as SRAM. DRAM uses less power than SRAM.

There are some other memory technologies are also available which are below…
