Talk:EFuse

Prologue

The Droid X doesn't implement eFuses, it uses the ones implemented in the TI OMAP processor which is already referenced. —Preceding unsigned comment added by 67.110.119.246 (talk) 19:18, 19 July 2010 (UTC)

Are you seriously using a post in a forum discussion- one that cites this very page to back up its claim- as proof that eFUSE technology is being implemented in the Motorola Droid X? Acedea9 (talk) 17:02, 15 July 2010 (UTC)

This article is very inaccurate. There are several efuse technologies, not all are reversible. And even if they are it is not given that the implementation permits reversing it through JTAG. Nor is it given that the device even implements JTAG.

Efuses are found on nearly any medium or more complexity digital integrated circuit —Preceding unsigned comment added by 12.2.202.16 (talk) 18:39, 15 July 2010 (UTC)

Is it any different from NOR flash memory? L29Ah (talk) 20:33, 9 February 2019 (UTC)

TODO: Citations

Hello, I came to add information about the Nintendo Switch in this article and noticed the lack of inline citations. Is anyone here able to find some info on this and add them to the work cited for inline citations? Currently there is only an article about blown fuses in the Switch at the moment. thank you 🐺RooWritten🐺 _TALK 23:54, 26 June 2019 (UTC)

Just another use case

Tesla uses fuses to store the hash of a root CA used as a trust anchor for the following boot process.

Merge with Programmable_ROM?

The lede currently starts with

In computing, an eFuse (electronic fuse) is a microscopic fuse put into a computer chip. This technology was invented by IBM in 2004 to allow for the dynamic real-time reprogramming of chips

From the Programmable_ROM page:

The PROM was invented in 1956 by Wen Tsing Chow, working for the Arma Division of the American Bosch Arma Corporation in Garden City, New York. The invention was conceived at the request of the United States Air Force to come up with a more flexible and secure way of storing the targeting constants in the Atlas E/F ICBM's airborne digital computer. The patent and associated technology were held under secrecy order for several years while the Atlas E/F was the main operational missile of the United States ICBM force. The term burn, referring to the process of programming a PROM, is also in the original patent, as one of the original implementations was to literally burn the internal whiskers of diodes with a current overload to produce a circuit discontinuity.

It seems that the whole idea of blowing microscopic fuses to reprogram a chip was invented in 1956 by Wen Tsing Chow, and then in 2004 IBM came up with the idea that they could re-brand half a century old technology as something new by giving it a fancy name. If "eFuse" technology does indeed do anything that makes it different from a good old OTP-ROM then the article should explain that. Otherwise I think it should be merged with Programmable_ROM mentioning that some chips using OTP-ROM memory are being marketed as having "eFuse" technology. PoiZaN (talk) 15:24, 14 July 2024 (UTC)
