Make a one chip RAM (random access memory)

Hi,since this is my first instructable and English is not my mother language so please excuse me for mistakes.

This instructable I'm going to show you how to make a RAM to use with a micro-controller for storing data and it is also expandable and uses only one IC and no other components. It is easy for any hobbyist to make.(COMMENT PLEASE) on to the next step!
