 Dynamic random access memory - Wikipedia, the free encyclopedia
The BIOS in some computers, and operating systems such as Linux, allow counting of detected and corrected memory errors, in part to help identify failing memory modules before the problem becomes catastrophic.
This memory was primarily used in graphic cards with Tseng Labs ET6x00 chipsets, and was made by MoSys.
VRAM is a dual-ported version of DRAM formerly used in graphics adaptors.

 random access memory - definition of random access memory in Encyclopedia
This is in contrast to sequential memory devices such as magnetic tapes, discs and drums, in which the mechanical movement of the storage medium forces the computer to access data in a fixed order.
Random Access Memory or RAM is a type of computer storage whose contents can be accessed in any order.
Core memory, which used wires attached to small ferrite electromagnetic cores, also had roughly equal access time (the term “core” is still used by some programmers to describe the RAM at the heart of a computer).

 High-Tech Dictionary Definition
(DRAM).A type of computer memory that is stored in capacitors on a chip and requires a refresh signal to be sent to it periodically.Most computers have DRAM chips, because they provide a lot of memory at a low cost.

 SDRAM - Synchronous Dynamic Random Access Memory
The clock is coordinated with the CPU clock so the timing of the memory chips and the timing of the CPU are "in synch." The synchronization eliminates time delays and allows for fast consecutive read and write capability, thereby increasing the overall performance of the computer.
The clock is co-ordinated with the CPU clock so the timing of the memory chips and the timing of the CPU are “in synch.” Synchronous DRAM saves time in executing commands and transmitting data, thereby increasing the overall performance of the computer.
SDRAM is replacing EDO DRAM in many newer computers.

 DRAM - a Whatis.com definition - see also: dynamic random access memory
Dynamic random access memory (DRAM) is the most common kind of random access memory (RAM) for personal computers and workstations.
DRAM is dynamic in that, unlike static RAM (SRAM), it needs to have its storage cells refreshed or given a new electronic charge every few milliseconds.
The network of electrically-charged points in which a computer stores quickly accessible data in the form of 0s and 1s is called memory.

 dynamic random access memory definition of dynamic random access memory in computing dictionary - by the Free Online ...
Today, this is the preferred way to buy memory for workstations and personal computers.
To reduce the pin count, thereby helping miniaturisation, DRAMs generally had a single data line which meant that a computer with an N bit wide data bus needed a "bank" of (at least) N DRAM chips.
The first commercially available DRAM chip was the Intel 1103, introduced in 1970.

 What is DRAM? - A Word Definition From the Webopedia Computer Dictionary
Pronounced dee-ram, DRAM stands for dynamic random access memory, a type of memory used in most personal computers.
Describes the types of memory packaging available and the issues involved in selecting and using memory packages and DRAM chips in a PC.
Covers technology types, memory speed and timing, packaging, error detection and correction, and the logical memory layout.

 Optical Dynamic Random Access Memory (407)
Since ODRAM is dynamic, i.e., nonpermanent, it will not replace magnetic storage, but may eventually be applied to workstations and desktop computers to complement other data storage technologies by providing fast access to massive data stores.
Templex Technology is developing an optical dynamic random access memory (ODRAM) device that can provide 100 gigabytes (one billion bytes) of storage capacity with entirely nonmechanical beam steering.
This capability will result in data access times of microseconds (millionths of a second) rather than milliseconds (thousandths of a second) common in magnetic disk storage technology today.

 Dynamic Random Access Memory - DRAM
Short for Dynamic Random Access Memory, DRAM is one of the most commonly found memory modules in PC compatible personal computers and workstations.
When using this type of memory, if the computer is powered off, the information within memory will be lost.
DRAM stores its information in a cell containing a capacitor and transistor; because of this design, these cells must be refreshed with new electricity every few milliseconds allowing the memory to keep its charge and hold the data as long as needed.

 Extended Data Out Dynamic Random Access Memory from FOLDOC
In early 1995, EDO DRAM was available for computers from Micron, Gateway 2000, and Intel Corporation; since then other manufactures followed suit.
EDO DRAM is primarily used with Intel's Pentium processors since with slower processors there is no significant performance gain.

 Process of fabricating dynamic random access memory cell - Patent 4987091
However, no n.sup.+ type region may be formed as the lower capacitor electrode, and a positive voltage level may be applied to the capacitor electrode for formation of an inversion layer which serves as the lower capacitor electrode.
The switching transistor selectively provides a channel between the source and drain regions 35 and 22", and a data bit in the form of electric charges is memorized into or read out from the storage capacitor.
This invention relates to a semiconductor memory device and, more particularly, to a process of fabricating a dynamic random access memory cell of one-transistor and one-capacitor type.

Increasing demand for high-density memories has necessitated the search for new materials with higher dielectric constants to satisfy the minimum charge storage density requirements.
In the current research work, it was demonstrated that by chemically modifying the tantalum pentoxide matrix, significant improvements in its electrical properties can be achieved which would enable the fabrication of a reliable high-density memory device.
Several materials such as Ta are being investigated to replace the currently used Si based oxide/nitride dielectrics.

 DRAM - Glossary - CNET.com
DRAM data resides in a cell made of a capacitor and a transistor.
DRAM is the Hershey's chocolate of readable/writable memory: it's not the best, but it's cheap, does the job, and is available almost everywhere you look.
The capacitor tends to lose data unless it's recharged every couple of milliseconds, and this recharging tends to slow down the performance of DRAM compared to speedier RAM types.
