memory (RAM) is one of the type of computer data storage. RAM is considered as
a volatile memory that means the stored data of information will be lost when
there will be no power to system. Adding to it, it is used by CPU when computer
is working to store data which is used to be very short period of time, but it
will not store any data or information permanently. The time need to read and
write data items varies drastically depending on their physical locations.
Moreover, RAM contains multiplexing circuitry, to join the information or data
lines to the specific storage for reading and writing. In this sophisticated
scenario, RAM devices use integrated circuits to store information.

In 1940’s,
the oldest form of RAM was in the very first computers. An array of magnetized
rings was relied by magnetic-core memory. By magnetizing each ring individually
data 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 nearly
thousands of vacuum tubes and contain a mercury memory and wire which is made
up of nickel delay lines, in 1945. In the middle of 1945 and 1954, number of
things such as delay lines, William tubes and magnetic drums were used as a
memory gadgets. In 1952, Core memory was invented. A core memory was a small
ring which is made up of ferrite, a ferromagnetic could be magnetized in both
directions. This type of different characteristic of core was abled it to carry
a bit of data or information, 1 or 2, depends on the direction of the magnetic

In 1968
company called Intel was started and manufacture large scale integrated
technology. In 1969, Shottky bipolar memory was the first victorious product by
the company, a 64-bit high-speed static random access memory introduced. Intel
was working on the 1102 and 1103, two designs for 1k dynamic RAM using three
transistors per memory cell. 1103, the world’s first 1k dynamic RAM, was
actually the changing point in the history of integrated circuit for the first
time significant amount of data could be stored on small single chip. It became
popular and replace core memories. In 1972, It was one of the large selling
semiconductor in the world. This uses very small transistors, made it as
possible to store large amount of information on a very small area. Albeit,
increase in memory density came to the cost of volatility: a constant power
supply is provided to maintain the behavior of each transistor.

Intel’s 1103
was the world’s first available dynamic RAM chip.
