hi, i would like to get detail ppt of silicon memory

Silicon Chips

Computers these days are made out of many billions of electronic components. The most important of these components is the transistor. Invented at the end of the 1940s, transistors allowed people to build electronic circuits (and simple computers) that didn't use large, delicate components called "valves". Transistors helped people to build smaller, cheaper computers that were faster and used a lot less power.
It was in the final years of the 1950s that people found out how to put numbers of electronic components onto a small, thin sheets of an element called silicon. These pieces of silicon were called Integrated Circuits (or ICs), then referred to as Silicon Chips, and later they were just called "chips".


As people got better at making silicon chips they started to put more and more electronic circuits onto them.

The chips themselves were encased in a black, ceramic material with lots of metal 'pins' sticking out that would allow them to be soldered onto a circuit board.

It was only a matter of time before people put enough electronic circuits onto a silicon chip to make a whole computer. This chip was called a Microprocessor: it contained the main parts of the central processing unit and it enabled people to make the small, fast computers that we use today.

The first microprocessors were made in the early years of the 1970s by the Intel Corporation. The first microprocessor was called the 4004 - it was designed to be a general-puprose, programmable chip that could be used for many different jobs.
