	Solid-state camera employing non-volatile charge storage elements - Patent 4025910
		Changes in the charge storage in each of the elements results in changes in the capacitance of the element; either the capacitance of the element or its charge state is sensed to indicate the state of the element for information storage purposes.
		A solid-state camera as claimed in claim 1 wherein a change of state of a storage element form a stable state to a quasi-stable state effects a change in the transconductance of the storage element and in which the means for sensing includes means for sensing any change in the transconductance of individual storage elements.
		The storage element 101 is originally at the capacitance value labeled A; a forward bias V.sub.B moves it to point B and, when the bias is removed, it moves to point C. It will then slowly relax from point C to point A (in a time period of 10.sup.5 seconds or more).

	VOLATILE - Definition
		Note: Substances which affect the smell with pungent or fragrant odors, as musk, hartshorn, and essential oils, are called volatile substances, because they waste away on exposure to the atmosphere.
		Alcohol and ether are called volatile liquids for a similar reason, and because they easily pass into the state of vapor on the application of heat.
		On the contrary, gold is a fixed substance, because it does not suffer waste, even when exposed to the heat of a furnace; and oils are called fixed when they do not evaporate on simple exposure to the atmosphere.

	Non-volatile storage device refresh time detector - US Patent 5852582 (Site not responding. Last check: 2007-10-21)
		A timing apparatus for monitoring when a memory array in a non-volatile storage device needs to be refreshed includes a programmable semiconductor device and detecting means for detecting when the amount of charge on the programmable semiconductor device has diminished to at most a threshold amount.
		Each non-volatile storage device is an integrated circuit and generally includes an array of memory cells, where each cell stores a bit of information, and also includes other logic for reading the stored information.
		In order to detect when a memory array needs to be refreshed and to overcome the problems of conventional timing circuitry, a system in accordance with the invention generally utilizes a floating gate transistor as a timing cell where the timing cell is similar to memory cells to be monitored.

	Protection circuit for storage of volatile data - Patent 4247913
		Recognizing the need for a way to preserve this volatile data in the event of a power interruption in order to avoid loss of data and the resulting disruption and complication in start-up procedure, the prior art has provided means for storing important volatile data in the event of such an interruption.
		This storage of volatile data can be utilized, for example, in the case of the occurrence of a failure in the power source which supplies power to the data system.
		Alternatively, the storage subroutine could be provided as part of an intentional turning off of the microprocessor and data system, with the intention of resuming operation later, at which time the contents of register 10 can be fed back into the microprocessor so that operation can resume utilizing data previously developed.

	Zvon - RFC 2975 [Introduction to Accounting Management] - Scaling and reliability
		In accounting systems without non-volatile storage, accounting data must be stored in volatile memory during the period between when it is generated and when it is transferred.
		For devices without non-volatile stage, this is typically determined by available memory; for devices with non- volatile storage the maximum polling interval is determined by the size of non-volatile storage.
		Without non-volatile storage, the polling model results in loss of accounting data due to device reboots, but not due to packet loss or network failures of sufficiently short duration to be handled within available memory.

		The medium can be used for memory-expensive operations, as a regular storage, or for handling certain types of sensitive data that are expected not to leave a physical trail on a hard disk or other non-volatile media.
		As opposed to traditional methods of parasitic data storage (P2P abuse, open FTP servers, binary Usenet postings), the use of this medium may or may not leave a trail of data (depending on a solution used) and specifically does not put any single system under a noticable load.
		The storage is not suitable for critical data that should be preserved at all costs, due to the risk of data being lost on network failure.

		Information is combined from the modifiable storage and the read-only storage and presented to the user such that the entire read-only storage information need not be copied into memory.
		Typically, however, the characteristics of the underlying physical storage media (which may be a magnetic disk, floptical, magnetic tape, or the like) permit modifications or writing of information and are not "non-modifiable" in the strict literal sense of that term.
		As used herein, "non-modifiable store (NMS)" refers to any storage which does not allow information or data to be changed whether this limitation is imposed by a physical constraint of the storage media or artificially imposed as an access control method.

		MEMS-based storage is an exciting new technology that could provide significant performance gains over current disk drive technology and at costs much lower than EEPROM technology.
		Based on MEMS (MicroElectroMechanical Systems), this non-volatile storage technology merges magnetic recording material and thousands of recording heads to provide storage capacity of 1-10 GB of data in under 1 cm^2 area with access times of under a millisecond and streaming bandwidths of over 50 Mbytes per second.

		Nonvolatile (sometimes written as "non-volatile") storage (NVS) - also known as nonvolatile memory or nonvolatile random access memory (NVRAM) - is a form of static random access memory whose contents are saved when a computer is turned off or loses its external power source.
		NVS is implemented by providing static RAM with backup battery power or by saving its contents and restoring them from an electrically erasable programmable ROM (EPROM).
		Some modems use NVS as a place to keep preset or user-specified phone numbers and modem profiles.

	The Volatile Storage Qualifier
		The compiler can mistakenly assume that the value is immutable and store it in a machine register as an optimization measure, rather than read it from the modem's port.
		The volatile qualifier instructs the compiler to read the value of the variable from its source (in this case, the modem port) every time it is accessed, instead of storing it in a faster processor register.
		The generated code may be less efficient in this case, but it is correct.
