Non-volatile memory

from Wikipedia, the free encyclopedia

As non-volatile memory (plural; singular: "non-volatile memory"; this is a loan-translation from the American-English " nonvolatile ... " or " non-volatile memory " , NVM for short ) - more precisely non-volatile data memory and (again more generally) also " persistent memory" so, translated as permanent memory or memory - to be in the electronic data processing , various data storage designated whose stored information remain permanently - even during the machine is not operating or not with electricity is supplied.

Nowadays, non-volatile memories are almost exclusively secondary memories - such as SSDs (and similar, older semiconductor memories such as EPROM and Flash memory ), but also magnetic ones , such as hard disks and (very rarely used) floppy disks , as well as optical ones , such as CDs and DVDs . In the early days of information technology, drum memory and core memory were used as non-volatile memories. In recent years, interest increases non-volatile random access memories (English non-volatile random access memory and also briefly NVRAM called). Examples of this class of RAM are FeRAM , MRAM and PCRAM .
