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.


Two and a Half Cubic Feet Held 32KB
The first widely used RAM employed magnetic cores strung together with multiple wires, and the cores held their content without power. About 30" high, this 32KB Dataram module was for a Data General minicomputer in 1967. See core storage.

Although large number of research have indicated that various kinds of nonvolatile memory properties (WORM and write-read-erase-read) and operation modes (unipolar and bipolar) have been observed in polythiohene-based memory devices, it still cannot provide a satisfactory explanation for the electrical conduction mechanism, because it is much more complex than in ordered inorganic materials, as most polymers are amorphous in nature [10].
