This is what is called dynamic working to retain the information. The memory controller helps in reading all the info before the discharge and writes it back. Microcontrollers or CPU comes into the picture and recharges all the capacitors, holding the information before they discharge. The problem with this container is that it has a leak that leads to an empty container within milliseconds. Now consider the capacitor as a container full of electrons- the presence of electrons is 1 and the empty container is 0. The transistors in the circuit act as a switch to change the states of the capacitor and read the information as well. The charged capacitor represents a 1 and 0 when discharged. The information stored in the DRAM is in the form of 0’s and 1’s. Then how does DRAM hold information for the CPU? As we know, capacitors have the tendency to discharge even in a continuous power supply, thus it starts losing the info within milliseconds. The DRAM stores information in the capacitors. The dynamic word comes from the retaining power of the DRAM. That is, in simple language, you can tamper with the data of RAM memory.ĭRAM Stands for Dynamic Random Access Memory, is a type of ram that consists of a memory cell made up of transistors and capacitors.Įach specific capacitor stores different bits of data that are integrated into a circuit. That is, RAM memory is the fastest in terms of processing this key.Īpart from this, it also has the option of writing as well as reading memory, whose RAM is also called read-write memory. Because no computer system can run without RAM memory.īut what makes RAM useful is that any information can be accessed quickly while running any program as compared to ROM. This memory is very powerful because the work being done in the computer at the present time is done by this memory and RAM memory is there in every type of computer system. The data stored in this memory is not stored for a long time because the stored data of this memory is automatically deleted as soon as the computer is shut down. If you understand the volatile memory in simple terms, then it is a forgetful memory, that is, the data of this memory is always deleted. RAM or Random Access Memory is used to store data, however, all the information is lost once the power supply is removed.
