 Avoid corruption in nonvolatile memory
The design of an embedded system with nonvolatile memory is, therefore, an exercise in minimizing the occurrence and impact of data corruption.
The key to using nonvolatile memory effectively in an embedded system is to add layers of protection against corruption to the system, so the probability of a corrupting event occurring becomes negligibly small.
Nonvolatile memory usually corrupts with the address pins in the high or low state, and preferentially corrupt at the top and bottom of their address range.

 Infineon designs smallest nonvolatile flash memory chip   (Site not responding. Last check: 2007-10-23)
The memory cell, measuring 20 nanometers or approximately 5,000 times thinner than a human hair, could lead to the availability of memory chips with a capacity of 32G bits, which is eight times the capacity of chips currently available on the market, Infineon said yesterday.
Nonvolatile flash memory chips are becoming increasingly popular as mass storage media for devices such as digital cameras, camcorders and USB (Universal Serial Bus) sticks.
The most advanced nonvolatile flash memory devices available today, according to Infineon, are able to permanently store one or two bits of information per memory cell without a supply of voltage.

 A Nonvolatile Memory Overview
A nonvolatile memory (NVM) device is a MOS transistor that has a source, a drain, an access or a control gate, and a floating gate.
Nonvolatile memory cells have some important functional characteristics, which are used to evaluate the performance of the cell.
In nonvolatile memories, IPD is used to isolate the floating gate from other electrodes (control gate, source, drain, and the substrate) and hence, should be defect-free to prevent charge leakage from the floating gate.

 Nonvolatile Holographic Storage in Doubly Doped LiNbO
Nonvolatile holograms can be written with red light in the presence of ultraviolet.
The key to nonvolatile storage according to the present method is a different exposure schedule in which one illuminates the crystal with ultraviolet and red light simultaneously and waits until saturation is reached, then switches the ultraviolet light off.
Thus, in the present method, a nonvolatile hologram is recorded by exposing the crystal simultaneously to incoherent ultraviolet light and coherent interfering beams of red light.

 Global distribution and sources of volatile and nonvolatile aerosol in the remote troposphere
CN number densities in all regions are largest when the atmosphere is devoid of nonvolatile particles.
Nonvolatile aerosols behave in a manner similar to tracers of combustion (CO) and photochemical pollution (peroxyacetylnitrate (PAN)), implying a continental pollution source from industrial emissions or biomass burning.
Results from an aerosol microphysical model suggest that the coagulation of fine volatile particles with fewer but larger nonvolatile particles, of principally anthropogenic origin, is one possible explanation for this relationship.

 Virage nonvolatile memory to be built in logic process
Virage (Fremont, Calif.) is rolling out the embedded memory called Novea RAM on Monday (Feb. 25), touting it as a viable low-density alternative to flash or other types of integrated nonvolatile memory.
However, the drawback is that the design isn't as silicon efficient as higher-density nonvolatile memory, such as flash.
As the SoC era develops, Virage is hoping to cash in on a potentially lucrative niche market, in which low-density, lower-cost nonvolatile memory could be the choice for products ranging from encryption keys and chip IDs to the storage of configuration parameters in Bluetooth or 802.11 RF front-end chips.

 Portable Design - Challenge of real time in-system programmability   (Site not responding. Last check: 2007-10-23)
Nonvolatile storage, usually EEPROM or flash, has typically been used in complex PLDs (CPLDs) and a limited number of FPGAs.
One approach often adopted with SRAM and combined SRAM/nonvolatile devices is to sidestep this issue by first reprogramming the nonvolatile boot memory, then applying the new configuration the next time the power is cycled.
Also, if a design uses nonvolatile devices for which the programming must be applied directly to the device, this approach is not possible.

 SOCcentral: A Point/Counterpoint: SRAM vs. Nonvolatile FPGAs (SemiView, Inc. 6089)   (Site not responding. Last check: 2007-10-23)
The arguments of both debaters are thought provoking and informative, with each position not nearly as "fl and white" as you may expect.
To the first order, nonvolatile is appropriate for "instant-on" functions that must be operational on power-up, and volatile devices are suited to functions that will change in real-time as adaptive hardware.
To the second order, nonvolatile devices are generally smaller than SRAM devices, so the size of the design often dictates the implementation fabric.

It is true that the addition of a nonvolatile solute causes a lowering in the vapor pressure of a solution.
The error lies in attributing this vapor pressure lowering to the "blocking" of surface sites by nonvolatile particles.
This is a totally fallacious argument for a number of reasons and the true explanation is to be found in the entropy changes that occur as a nonvolatile solute is added to a solution.
