STATIC RAM
If we want to store a large amount of data we use an array of many flip-flops on a single chip. Such a large array is normally called a memory. Each flip-flop can store a single bit of data in it. Flip-flop has the capability to store data into it individually. The set or reset mode of flip flop, depends on whether the bit is a 0 or 1. This process is called writing, because the art of storing data is just like as writing information on a paper. Each flip-flop can also be read to check whether the data stored there is 0 or 1. One RAM chip may comtain several hundreds or thousands of flip-flops on it. For the purpose of writing to or read from any particular flip-flop among these, we require knowing its address.
