Conditionally evolving memory for computers

Most of the contemporary computers are evolved from the Von-Neumann architecture which was built based on the Charles Babbage´s mill and the store concept. Thereby this architecture consists of a processor and a memory where the memory improves the processing power. Later different kinds of smaller memories such as registers & caches were introduced to enhance the processing power of the computer. It is an existing great research challenge to improve the performance of the computer and in doing so, there is a trend to design computing models by imitating human mind.
