Direct Memory Access (DMA) is a capability provided by some computer bus architectures that enables data to be sent directly from an attached device, such as a disk drive, to the main memory on the computer'smotherboard. The microprocessor, or central processing unit (CPU), is freed from i...
Direct Memory Access can also be used for “memory to memory” to copy or move data in memory. It can transfer expensive memory operations (such as large copies or scatter-gather operations) from the CPU to a dedicated DMA engine. DMA is important in network-on-chip and memory computing a...
Direct memory access facilitates data transfers between peripheral devices and their hosts. Learn DMA meaning with Techopedia.
Short for direct memory access, a technique for transferring data from main memory to a device without passing it through the CPU. Computers that have DMA channels can transfer data to and from devices much more quickly than computers without a DMA channel can. This is useful for making quick...

What is Remote Direct Memory Access (RDMA)? Remote Direct Memory Access is a technology that enables two networked computers to exchange data in main memory without relying on the processor,cacheor operating system of either computer. Like locally based Direct Memory Access (DMA), RDMA improves ...

Optane memory is based on 3D XPoint technology jointly developed by Intel and Micron. 3D XPoint (pronounced CrossPoint) seeks to fill the functional gap between fast but volatile (and relatively expensive) DRAM and less costly, non-volatile NAND Flash. While a revolution in its day, NAND Flash...

Understanding Direct-Access Brokers As noted above, direct-access brokers connect traders with markets. According to Charles Schwab, direct access is "a feature that allows trades to be placed directly through an electronic communications network, market maker or exchange."1This is done efficiently, ...
