RAM

The first RAM chip in the world was built in 1951 by Dr. Bernard Widrow who tried it on a Whirlwind Computer. The computer would be used to track incoming Russian bombers using data from radar stations on the west coast . It is now the most common type of memory found in computers and printers. RAM stands for Random Access Memory, synonymous with "main memory", and serves as temporary memory for the computer. This means that whenever the computer is turned off, the memory is erased. When you turn the computer on, a completely new set of data is stored. This is because any byte of memory can be accessed without using preceding bytes.


RAM is made up of micro chips that are integrated circuits. These are made of millions of transistors and capacitors. A capacitor is like a bucket that can store electrons. To store one 1, the bucket needs to be full of electrons. To store one 0, the bucket needs to be empty of electrons. In milliseconds, the bucket is able to empty and refill multiple times with eletrons.


There are two types of RAM, DRAM (Dynamic Random Access Memory), and SRAM (Static Random Access Memory). DRAM is more common, mainly because it is cheaper. SRAM, some would say, is a lot better, because it is way faster, giving access times at 10 nanoseconds (whereas DRAM only supports acces times of ~60 nanoseconds). Both have their pros and cons, but they both lose their contents once the power is turned off (hence, random access).



Israeli researchers found a way to build Ram with a giant capacity and small dementions. They built it with molicules of carbon. Because of this, it may possible to make Smartphones with more than 8GB of RAM in the future!

YAYYYY WE LOVE RAM.
