The Ultra DMA (Ultra Direct Memory Access, UDMA) modes were the fastest method used to transfer data through the ATA hard disk interface, usually between...

random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM)...

the data. Because of this inefficiency, the DMA (and eventually Ultra Direct Memory Access (UDMA)) interface was created to increase performance. The simple...

Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM...

random access memory (RAM), meaning that when the computer is shut down, anything contained in RAM is lost. However, most forms of non-volatile memory have...

Technology Attachment (ATA) controller) and an ATA device until Ultra Direct Memory Access (UDMA) was implemented. Single/Multiword DMA took over from Programmed...

irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks and magnetic tape)...

town in the Indian state of Kerala. Ultra Direct Memory Access (UDMA), a set of standards for Direct Memory Access (DMA) data transfer This disambiguation...

of semiconductor memory have the property of random access, which means that it takes the same amount of time to access any memory location, so data...

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually...

Magnetoresistive random-access memory (MRAM) is a type of non-volatile random-access memory which stores data in magnetic domains. Developed in the mid-1980s...

Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but using a ferroelectric layer instead of a dielectric...

as it becomes unavailable on power-down. Most general-purpose random-access memory (RAM) is volatile. There are two kinds of volatile RAM: dynamic and...

methods, such as memory mapping, do not affect the direct memory access (DMA) for a device, because, by definition, DMA is a memory-to-device communication...

Synchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM) is any DRAM where the operation of its external pin interface is coordinated...

flash memory is that it can endure only a relatively small number of write cycles in a specific block. NOR flash is known for its direct random access capabilities...

Examples of volatile memory are dynamic random-access memory (DRAM) used for primary storage and static random-access memory (SRAM) used mainly for...

C-RAM or CRAM (chalcogenide RAM)) is a type of non-volatile random-access memory. PRAMs exploit the unique behaviour of chalcogenide glass. In PCM, heat...

Resistive random-access memory (ReRAM or RRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance...

reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which...
