Ram (Random Access Memory)

Ram (Random Access Memory) is also called Temporary Memory. It is used to store temporary memory in computer systems or Embedded Devices. It keeps the data stored in it until it is given voltage supply. And as soon as the voltage supply is removed, all its data is erased. And again if it is given power supply then it starts to retain the data.

RAM speed depends on the size of the RAM, the higher the size of the RAM, the faster the speed of the RAM will be. It Depends on You What size do you need RAM?  Generally, the Embedded Devices comes with a fixed amount of RAM, with microcontrollers.

Programming string data and other types of data are stored in it. You can also say RAM as a temporary storage memory. Because it stores the data in it for a shorter duration of time. until the power supply is given to it.

Types of RAM (Random Access Memory)

Two types of RAM are available in the market.
  1.  SRAM (Static RAM)
  2.  DRAM (Dynamic RAM)


  1. SRAM(Static RAM)  Static RAM does not require constant voltage supply to store the data. This RAM can keep the data stored inside it after the voltage supply is removed. The speed of this RAM is much faster than DRAM. This RAM is made with a special combination of transistors and capacitors. That's because it's expensive, compared to DRAM.
  2. DRAM(Dynamic RAM) Dynamic RAM does require constant voltage supply to store the data.This RAM cannot keep the data stored inside it after the voltage supply is removed. The speed of this RAM is much slower than SRAM. This RAM is Inexpensive than SRAM. That's because all the fabricators use this RAM instead of SRAM.

Embedded  System Tutorial Online What is Embedded System? The Embedded Systems Devices are designed to replace the complexity of the computer system. And they are designed to perform a specific dedicated task. It is a combination of hardware and software. which is used to perform a specific task on a large system in the industrial machine, in the camera, in the household appliances, in industrial devices, in the traffic signals in security systems, in the barcode scanner all are possible places for an Embedded System. Why is the Embedded System becoming so important ? Reason for the Embedded System is being so important is that each day we become more dependent on Digital Information technology & Embedded System Technology. Nowadays everyone wants to do their job as quickly as possible and that too without any extra effort. Nowadays everyone wants to do their job by pressing a button. For example, if I press a button then...

Getting Started With Embedded System

Getting Started With Embedded System We have already read in the previous tutorial what is the embedded system, and what is its importance and its applications. We will start with basics of Embedded System first.  As We Already aware that the Embedded System is computer or processor which is designed to execute particular responsibilities. There are 2 following main segments of Embedded Systems.   Hardware  Software Hardware:-  Embedded System Hardware hardware is used to perform controlling operation in Embedded System. such controlling the speed of a motor, controlling the brightness of the LED, etc. Embedded systems require different types of hardware to execute a task. Such as microprocessors, microcontrollers, or resistors, capacitors, sensors, relay etc. We will deeply learn to use all these components in this tutorial periodically. Software:-  Embedded System Software Software...
