produced specifications for standard interface to NAND flash chips.
The Open NAND Flash Interface Working Group (
with a lower case "i"), is a consortium of technology companies working to develop open standards for NAND flash memory and devices that communicate with them. The formation of
was announced at the Intel Developer Forum in March 2006.
consortium included manufacturers of NAND flash memory such as Hynix, Intel, Micron Technology, Phison, SanDisk, Sony and Spansion.
A group called the Open NAND Flash Interface Working Group (
) has developed a standardized low-level interface for NAND flash chips. This allows interoperability between conforming NAND devices from different vendors. The
specification version 1.0 was released on 28 December 2006. It specifies:
created the Block Abstracted NAND addendum specification to simplify host controller design by relieving the host of the complexities of ECC, bad block management, and other low-level NAND management tasks. The
Block Abstracted NAND revision 1.1 specification adds the high speed source synchronous interface, which provides up to a 5X improvement in bandwidth compared with the traditional asynchronous NAND interface.
Clobazam (marketed under the brand names Frisium, Urbanol,
and Tapclob ) is a benzodiazepine that has been marketed as an anxiolytic since 1975 and an anticonvulsant since 1984.
Version 1.0 of this specification was released on December 28, 2006, and made available at no cost from the
group is supported by major NAND flash manufacturers, including Hynix, Intel, Micron Technology, and Numonyx, as well as by major manufacturers of devices incorporating NAND flash chips.
Overdose and intoxication with benzodiazepine, including
, may lead to CNS depression, associated with drowsiness, confusion and lethargy, possibly progressing to ataxia, respiratory depression, hypotension and rarely coma or death. The risk of a fatal outcome is increased in cases of combined poisoning with other CNS depressants, including alcohol.
Two major flash device manufacturers, Toshiba and Samsung, have chosen to use an interface of their own design known as Toggle Mode (and now Toggle V2.0). This interface isn't pin-to-pin compatible with the
specification. The result is a product designed for one vendor's devices may not be able to use another vendor's devices.
Phison claims to have produced the earliest "USB flash removable disk," dubbed "Pen Drive," in May 2001. Phison is a member of the Open NAND Flash Interface Working Group (
), which aims to standardize the hardware interface to NAND flash chips.
It was first approved by the FDA under the same brand name in October 2012 and then in June 2015 for the same uses as those in Europe; it was one of four new drugs for epilepsy approved between 2010 and 2016, along with clobazam (
), ezogabine (Potiga), and eslicarbazepine (Aptiom).
The first details of a new standard for accessing non-volatile memory emerged at the Intel Developer Forum 2007, when NVMHCI was shown as the host-side protocol of a proposed architectural design that had Open NAND Flash Interface Working Group (
) on the memory (flash) chips side. A NVMHCI working group led by Intel was formed that year. The NVMHCI 1.0 specification was completed in April 2008 and released on Intel's web site.
The group's goals did "not" include the development of a new consumer flash memory card format. Rather,
seeks to standardize the low-level interface to raw NAND flash chips, which are the most widely used form of non-volatile memory integrated circuits (chips); in 2006, nearly one trillion MiB of flash memory was incorporated into consumer electronics, and production was expected to double by 2007. , NAND flash memory chips from most vendors used similar packaging, had similar pinouts, and accepted similar sets of low-level commands. As a result, when more capable and inexpensive models of NAND flash become available, product designers can incorporate them without major design changes. However, "similar" operation is not optimal: subtle differences in timing and command set mean that products must be thoroughly debugged and tested when a new model of flash chip is used in them. When a flash controller is expected to operate with various NAND flash chips, it must store a table of them in its firmware so that it knows how to deal with differences in their interfaces. This increases the complexity and time-to-market of flash-based devices, and means they are likely to be incompatible with future models of NAND flash, unless and until their firmware is updated.
