Random-accessmemory (RAM) is one of the type of computer data storage. RAM is considered asa volatile memory that means the stored data of information will be lost whenthere will be no power to system.
Adding to it, it is used by CPU when computeris working to store data which is used to be very short period of time, but itwill not store any data or information permanently. The time need to read andwrite data items varies drastically depending on their physical locations.Moreover, RAM contains multiplexing circuitry, to join the information or datalines to the specific storage for reading and writing.
In this sophisticatedscenario, RAM devices use integrated circuits to store information. History orbackground of RAMIn 1940’s,the oldest form of RAM was in the very first computers. An array of magnetizedrings was relied by magnetic-core memory. By magnetizing each ring individuallydata can be stored. If the rings were separate, which results large amount of installations.A single ring can store a single bit of information.
ENIAC computer used nearlythousands of vacuum tubes and contain a mercury memory and wire which is madeup of nickel delay lines, in 1945. In the middle of 1945 and 1954, number ofthings such as delay lines, William tubes and magnetic drums were used as amemory gadgets. In 1952, Core memory was invented. A core memory was a smallring which is made up of ferrite, a ferromagnetic could be magnetized in bothdirections. This type of different characteristic of core was abled it to carrya bit of data or information, 1 or 2, depends on the direction of the magneticcharge.
In 1968company called Intel was started and manufacture large scale integratedtechnology. In 1969, Shottky bipolar memory was the first victorious product bythe company, a 64-bit high-speed static random access memory introduced. Intelwas working on the 1102 and 1103, two designs for 1k dynamic RAM using threetransistors per memory cell. 1103, the world’s first 1k dynamic RAM, wasactually the changing point in the history of integrated circuit for the firsttime significant amount of data could be stored on small single chip. It becamepopular and replace core memories.
In 1972, It was one of the large sellingsemiconductor in the world. This uses very small transistors, made it aspossible to store large amount of information on a very small area. Albeit,increase in memory density came to the cost of volatility: a constant powersupply is provided to maintain the behavior of each transistor. Intel’s 1103was the world’s first available dynamic RAM chip.
