Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged .these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically.The advantage of DRAM is its structural simplicity. only one transistor and a capacitor are required per bit, compared to six transis ....etc

It is a step towards a new breed of computer chips that couple memory with information processing. Such chips retain data when computer is turned off, eliminating the time-consuming process of booting up information from hard drive to processor. If we can make semiconductor based magnetic memories when we turn on computer it would be like a TV set-all information will be there with no need for reloading the operating system. All spintronic computers eliminate the need for parallel processing. Computing could be accelerated and customized with r ....etc

Ferroelectric Random Access Memory
Abstract
Ferroelectric Random Access Memory Before the 1950€„¢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 emu ....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.

Resistive random-access memory (RRAM) is a new non-volatile memory type . Basic idea is that a dielectric, which is normally insulating can be made to conduct through a filament or conduction path formed after application of a sufficiently high voltage. The conduction path formation can arise from different mechanisms, including defects, metal migration, etc. Once the filament is formed, it may be reset (broken, resulting in high resistance) or set (re-formed, resulting in lower resistance) by an appropriately applied voltage. Different forms o ....etc

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

Magnetic Random Access Memory

MRAM is a nonvolatile random access memory which uses magnetic storage and magnetoresistance (MR) to read the stored data. Magnetoresistive material is a resistor made of common ferromagnetic material which will change in resistance in the presence of a magnetic field. The magnetoresistive property gives a small but sufficient signal to distinguish between a 1 and 0. MRAM results from combining MR storage elements with standard semiconductor fabrication processes. ....etc
