C不正确。因为直接内存访问(direct memory access,DMA)是指不使用CPtJ而在输入/输出(I/O)设备和系统内存之间传输指令和数据的方式。这大大提高了数据传输速度。DMA基本上是通过利用计算机系统内的其他处理能力保证多个单指令得到解释和执行,从而达到减轻CPU负担的目的。这不是微处理器技术的进步。 知识模块:安全体系...
There are multiple types of memory available to a computer. It will operate differently depending on the type of primary memory used, but in general, semiconductor-based memory is most associated with memory. Semiconductor memory will be made of integrated circuits with silicon-based metal-oxide-se...
Primary memory:The main drawbacks of primary memory are that it has a relatively low storage capacity and is volatile, which means that data saved in primary memory is only temporary and is lost when the computer or laptop is turned off and no longer powered. Secondary Memory:Although the inf...
In EPROM, one can program the memory chip and erase it thousands of times. This is especially necessary during the development of the prototype of amicroprocessor-based project. CMOS UV-EPROM IC A widely used EPROM is calledUV-EPROM, where UV stands for ultraviolet. The only problem with UV...
The universal memory card contains a common transfer interface (81), an interface/converter (82), a microprocessor (83) and a flash memory (86). The common unit handles a combination of USB lines and data lines (D0-D3). Initialization signals are fed through the MF1 and MF2 lines. ...

L2 is a secondary type of cache memory. L2 cache has more capacity than L1. It is located on a computer microprocessor. The processor searches Instructions in the L1 cache, if required data or instructions not found then it searched into L2 cache. The high-speed system bus interconnecting th...
The construction of memristor is shown below. It is a two terminal component and thememristor workingis, its resistance mainly lies on the magnitude, applied voltage, and polarity. As the voltage is not applied, then the resistance leftover, and this makes this as a non-linear and memory co...
main memory in a computer, also known as internal memory or internal storage. Accessing data from primary memory is pretty fast and it is either volatile like RAM or non-volatile like ROM. The capacity of primary memory is also limited and generally smaller when compared to secondary memory. ...
Memory Chips From the perspective of functionality,semiconductormemory chips store data and programs on computers and data storage devices. Random-access memory (RAM) chips provide temporary workspaces, whereas flash memory chips hold information permanently unless erased. Read-only memory (ROM) and ...
