ABSTRACT
While magnetic and semi-conductor based information storage devices have been in use since the middle 1950â„¢s, todayâ„¢s computers and volumes of information require increasingly more efficient and faster methods of storing data. Among the most promising of the new alternatives are photopolymer-based devices, holographic optical memory storage devices, and protein-based optical memory storage using rhodopsin , photosynthetic reaction centers. This paper focuses mainly on protein-based optical memory storage using the photosen ....etc

INTRODUCTION

Before the 1950â„¢s, ferromagnetic cores were the only type of random-access, nonvolatile memories available. A core memory is a regular array of tiny magnetic cores that can be magnetized in one of two opposite directions, making it possible to store binary data in the form of a magnetic field. The success of the core memory was due to a simple architecture that resulted in a relatively dense array of cells. This approach was emulated in the semiconductor memories of today (DRAMâ„¢s, EEPROMâ„¢s, and FRAMâ„¢s). ....etc

Imagine a time when your mobile will be your virtual assistant and will need far more than the 8k and 16k memory that it has today, or a world where laptops require gigabytes of memory because of the impact of convergence on the very nature of computing. How much space would your laptop need to carry all that memory capacity? Not much, if Intel's project with Thin Film Electronics ASA (TFE) of Sweden works according to plan. TFE's idea is to use polymer memory modules rather than silicon-based memory modules, and what's more it ....etc

Random access memory (RAM) is the best known form of computer memory. RAM is considered random access because you can access any memory cell directly if you know the row and column that intersect at that cell.

As processors and buses roughly double their data capacity every three years (Mooreâ„¢s Law), data storage has struggled to close the gap. CPUs can perform an instruction execution every nanosecond, which is six orders of magnitude faster than a single magnetic disk access. Much research has gone into finding hardware and software solutions to closing the time gap between CPUs and data storage. Some of these advances include cache, pipelining, optimizing compilers, and RAM. As the computer evolves, so do the applications that computers are ....etc

You hit the power button on your television and it instantly comes to life. But do the same thing with your computer and you have to wait a few minutes while it goes through its boot-up sequence. Why can't we have a computer that turns on as instantly as a television or radio? IBM, in cooperation with Infenion, is promising to launch a new technology that will eliminate the boot-up process. Magnetic random access memory (MRAM) has the potential to store more data, access that data faster and use less power than current memory technologies.

INTRODUCTION

We are now living in a world driven by various electronic equipments. Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. Semi conductors consist of array of transistors with each transistor being a simple switch between electrical 0 and 1. Now often bundled together in there 10â„¢s of millions they form highly complex, intelligent, reliable semiconductor chips, which are small and cheap eno ....etc
