An acronym for Direct Memory Access, a technique that passes data directly from RAM to the device, bypassing the CPU and saving processing cycles. In this bus architecture, the CPU can communicate with L2 cache directly on a bus that is independent of the system bus. Error checking and correcting memory is less tolerant of errors, allowing the detection and correction of single-bit errors. ECC memory can also detect multiple bit errors. An acronym for Extended Industry Standard Architecture.
Flash memory is used in cameras, pagers, cellphones and other devices of that ilk.
