A CDE Definition
With regard to computer storage, including hard drives, solid state drives (SSDs) and USB drives, it means that the content is not lost when the power is turned off. See non-volatile memory.
Memory chips that hold their content without power being applied. It may refer to chips that are not changeable, such as ROMs and PROMs, or to chips that can be rewritten many times such as flash memory. However, USB flash drives, along with hard drives and solid state drives (SSDs), are non-volatile storage devices, not non-volatile memory. See ROM, PROM, memory types, storage vs. memory and future memory chips.
