When memoire flash pci FG is charged with electrons, this charge screens the electric field from the CG, thus, increasing the threshold voltage V T1 of the cell.

This means that now a higher voltage V T2 memoire flash pci be applied to the CG to make the channel conductive. If the channel conducts at this intermediate voltage, the FG must be uncharged if it was charged, we would not get conduction because the intermediate voltage is less than V T2and hence, a logical "1" is stored in the gate. If the channel does not conduct at the intermediate voltage, it indicates that the FG is charged, and hence, a logical "0" is stored in the gate. The presence of a logical "0" or "1" is sensed by determining whether there is current flowing through the transistor when the intermediate voltage is asserted on the CG. In a multi-level cell device, which stores more than one bit per cell, the amount of current flow is sensed rather than simply its presence or absencein order to determine more precisely the level of charge on the FG. This, in turn, changes the drain-source current that flows through the transistor for a given gate voltage, which is ultimately used to encode a binary value.

Memoire flash pci Fowler-Nordheim tunneling effect is reversible, so electrons can be added to or removed from the floating gate, processes traditionally known as writing and erasing. Despite the need for relatively high programming and erasing voltages, virtually all memoire flash pci chips today require only a single supply voltage and produce the high voltages using on-chip charge pumps. Over half the energy used by a 1. In NOR flash, each cell has one end connected directly to ground, and the other end connected directly to a bit line.

NOR flash continues to be the technology of choice for embedded applications requiring a discrete non-volatile memory device. A single-level NOR flash cell in its default memoire flash pci is logically equivalent to a binary "1" value, because current will flow through the channel under application of an appropriate voltage to the control gate, so that the bitline voltage is pulled down.


To erase a NOR flash cell resetting it to the "1" statea large voltage of the opposite polarity is applied between the CG memoire flash pci source terminal, pulling the electrons off the FG through quantum tunneling. The erase operation can be performed only on a block-wise basis; all the cells in an erase segment must be erased together.


Programming of NOR cells, however, generally can be performed one byte or memoire flash pci at a time. Compared to NOR flash, replacing single transistors with serial-linked groups adds an extra level of addressing. Bit-level addressing suits bit-serial applications such as hard disk emulationwhich access only one bit at a time. Execute-in-place applications, on memoire flash pci other hand, require every bit in a word to be accessed simultaneously. This requires word-level addressing.

Flash memory vs. RAM: What's the difference?

To read data, first the desired group is selected in the same way that a single transistor is selected from a NOR array. Typical applications for serial flash include storing firmware for hard drivesEthernet controllers, DSL modemswireless network devicesmemoire flash pci. One more recent application memoire flash pci flash memory is as a replacement for hard disks. Flash memory does not have the mechanical limitations and latencies of hard drives, so a solid-state drive SSD is attractive when considering speed, noise, power consumption, and reliability. Flash drives are gaining traction as mobile device secondary storage devices; they are also used as substitutes for hard drives in high-performance desktop computers and some servers with RAID and SAN architectures.

There remain some aspects of flash-based SSDs that make them unattractive.

The cost per gigabyte of flash memory remains significantly higher than that of hard disks. For relational databases or other systems that require ACID transactions, even a modest amount of flash storage can offer vast speedups over arrays of disk drives. The first flash-memory based PC to become available was the Sony Vaio UX90, announced for pre-order on 27 June and began shipping in Japan on 3 July with a 16Gb flash memory hard drive. A solid-state drive was offered as an option with the first MacBook Memoire flash pci introduced inand from onwards, all models shipped with an SSD. Starting in lateas part of Intel 's Ultrabook initiative, an increasing number of ultra-thin laptops are being shipped with SSDs standard. There are also hybrid techniques such as hybrid drive and ReadyBoost that attempt to combine the advantages of both technologies, using flash as a high-speed non-volatile cache for files on the disk that are often referenced, but rarely modified, such as application and operating system executable files.

As ofthere are attempts to use flash memory as the main computer memory, DRAM. An article from CMU in writes that "Today's flash devices, which do not require flash refresh, have a typical retention age of 1 memoire flash pci at room temperature. The phenomenon can be modeled by the Arrhenius equation.

Some FPGAs are based on flash configuration cells that are used directly as programmable switches to connect internal elements together, using the same kind of floating-gate transistor as the flash data storage cells in data storage devices. The memoire flash pci competition among the top few manufacturers only adds to the aggressiveness in shrinking the design rule or process technology node.

The decrease in endurance and increase in uncorrectable bit error rates that memoire flash pci feature size shrinking can be compensated by improved error correction mechanisms.
