A. VOLATILE MEMORY Volatile memory, also known as volatile storage, is computer memory that requires power to maintain the stored information, unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as term 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. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory. The main memory (the RAM) in personal computers is Dynamic RAM (DRAM), as is the RAM of home game†¦show more content†¦Z-RAM has been licensed by Advanced Micro Devices for possible use in future microprocessors. Innovative Silicon claims the technology offers memory access speeds similar to the standard six-transistor SRAM cell used in cache memory but uses only a single transistor, therefore affording much higher packing densities. Z-RAM relies on the floating body effect, an artifact of the SOI process technology which places transistors in isolated tubs (the transistor body voltages float with respect to the wafer substrate underneath the tubs). The floating body effect causes a variable capacitance to appear between the bottom of the tub and the underlying substrate, and was a problem that originally bedeviled circuit designs. The same effect, however, allows a DRAM-like cell to be built without adding a separate capacitor, the floating body effect taking the place of the conventional capacitor. Because the capacitor is located under the transistor (instead of adjacent to, or above the transistor as in conventional DRAMs), another connotation of the name Z-RAM is that it extends in the negative z-direction. †¢ TTRAM Twin Transistor RAM (TTRAM) is a new type of computer memory in development by Renesas. TTRAM is similar to conventional one-transistor, one-capacitor DRAM inShow MoreRelatedComputer Memory3238 Words   |  13 PagesComputer Memory 1.Introduction: Just like humans, computers rely a lot on memory. They need to process and store data, just like we do. However, computers store data in digital format, which means the information can always be called up exactly the way it was stored. computer memory - an electronic memory device; a memory and the CPU form the central part of a computer to which peripherals are attached 1.1History of memory: In the early 1940s, memory technology mostly permitted a capacityRead MoreComputer Memory1614 Words   |  7 PagesComputer Memory Basics Although memory is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage. If your computers CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. When the information is kept in memory, the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above, the CPU accesses memory accordingRead MoreThe Computer Memory Interference Test Essay1356 Words   |  6 PagesIntroduction The Computer Memory Interference Test (CMIT) is a test that is designed to evaluate how memory is affected by a myriad of different variables. With results from this test, scientists are able to determine if an individual has a serious memory disorder such as Alzheimer’s, or other cognitive disorders such as Autism. This test can also determine how memory is affected by different cultures and lifestyles. This study will concentrate on lifestyle; more specifically, it will focus on theRead MoreMemory And Memory Of Computers868 Words   |  4 Pages Memory Have you ever wanted to know how certain files, documents and so on are being saved and what led this to occur? The memory of computers is quite fascinating and there is so much that goes into saving something on a computer. There are different types of memory that is found on computers that is needed to make things work and that would be acceptable to the user. The main two that is quite known in the computer world would be Primary and Secondary memory. There are 2 typesRead MoreComputer Science : Memory Management1149 Words   |  5 Pages Memory Management Navid Salehvaziri Virginia International University â€Æ' Abstract Memory management is a field of computer science that involves the act of managing computer memory to use it more efficient. That means how the computer allocate portion of memory to programs at different levels of priority to make faster program execution regard to memory space limitation. There are many techniques that are developed to reach this goal at many levels. This article try to introduce memory managementRead MoreComputer Memory Hacking Essay908 Words   |  4 PagesComputer Memory Hacking NAME Professor CIS 106 November 20, 2014 Technology continues to evolve exponentially. However these technological advancements continue to pose a threat to both individuals and information resources of companies and governments.

There are two basic categories: short-term and long-term. A classic computer contains several types of memory including RAM, ROM, cache, and various long-term storage devices. Each type of computer memory serves a detailed function and purpose. Computer memory is dignified in bytes. A single byte is made up of a series of 1s and 0s normally traveling in sets of eight. These eight 0s and 1s areRead MoreComputer Security : Memory Controlr Overflow731 Words   |  3 Pagesbuffers, or memory allocations exploits eventually giving the attacker full control over a compromised system. This takes place when a process or programme writes or attempts to write data onto a static sized memory block than it was initially allocated. By taking advantage of the buffer overflow attacker are always aiming to completely take control of the whole system by elevating their privileges to the Admin rights. To successfully attain this they identify a function pointer in memory that theyRead MoreAn Array Is Stored In A Continuous Sequential Memory Computers762 Words   |  4 Pagesrepresented in a larger format requires more complex circuitry and more time for executing the codes.
