The information stored in this type of memory is lost when the power supply to the PC or laptop is switched off. It is generally known as the main memory or temporary memory or cache memory or volatile memory of the computer system.

A random access memory is a random-access memory device that allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory. RAM is typically used to store working data and machine code. RAM is the main memory in a computer and it is much faster to read from and write to than other kinds of storage such as a hard disk drive HDD and Solid state drive SDD or optical drive.

Dynamic RAM is the most common type of memory in use today. Inside a dynamic RAM chip, each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor. These are, of course, extremely small transistors and capacitors so that millions of them can fit on a single memory chip. The capacitor holds the bit of information -- a 0 or a 1 see How Bits and Bytes Work for information on bits. The transistor acts as a switch that lets the control circuitry on the memory chip read the capacitor or change its state. A capacitor is like a small bucket that is able to store electrons.

Reading and writing in RAM is easy and rapid and accomplished through electrical signals. Simple and uses capacitors and very few transistors. Single block of memory requires 6 transistors Only one transistor. Charge leakage property Not present Present hence require power refresh circuitry Power consumption Low High. Its construction is comprised of two cross-coupled inverters to store data binary similar to flip-flops and extra two transistors for access control. It consumes less power.

SRAM vs DRAM: Know the Difference

Asked by Wiki User. These differences occur due the difference in the technique which is used to hold data. This marks the difference between their performance. They both are different from each other in many contexts like speed, capacity, etc. SRAM is an on-chip memory. The answer is actually fairly simple. In addition, SRAM design is relatively more flexible.

Dynamic random-access memory DRAM is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since even "nonconducting" transistors always leak a small amount, the capacitors will slowly discharge, and the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to static random access memory SRAM and other static types of memory.

What is the difference between static RAM and dynamic RAM?

In static RAM, a form of flip-flop holds each bit of memory. When the number of transistors is reduced, the size of the memory cell decreases.

    RAM is volatile. – non-volatile memory stores date even when power is removed. • ROM is non-volatile. • Static vs. Dynamic Memory. – Static: holds data as long.
