The victory of the losers, or the story of the creation of FLASH memory (part4)
Our main goal was not to change anything during the production process, and to solve the problem of how to place electrons on a floating shutter. Initially, we abandoned the…

Who needs these 64 bits?

On September 23, the new 64-bit processors from AMD, Athlon 64 3200+ and Athlon 64 FX-51 were officially announced. However, Internet users have long been familiar with these processors, since the first AMD64 (Opteron) architecture processors appeared at the beginning of this year. Yes, and some instances of Athlon 64 processors during this time, many were in the hands of.The EPOS also had the opportunity to comprehensively investigate the performance and capabilities of the new processors, as well as work out a new model of the graphics station. Accordingly, the results of their testing are available, and the architectural features of these processors are described in sufficient detail. Continue reading

The victory of the losers, or the story of the creation of FLASH memory (part3)

We were very happy and proud; you know, young engineers with their own hands were able to make the first “flip” chip. After some discussion between Gordon and Andy, Gordon said: “Guys, you have done a good job, but we will move on towards creating a monolithic chip.” Since I did not have other urgent projects, they also entrusted me with work on this chip.

The development of a monolithic microcircuit had its own problems. Continue reading

The victory of the losers, or the story of the creation of FLASH memory (part2)

This type of memory was made in the form of a two-dimensional matrix of conductors, at the intersection of which a thin jumper (20-30 μm) was created from metal or amorphous silicon. The programming of the microcircuits consisted of passing a large current pulse through an appropriate jumper that caused it to melt (burst). The likelihood of recovering torn jumpers was minimal. For greater reliability and eliminating the possibility of restoration of jumpers, the chip was subjected to thermal training (additional heating for a long time), and then it was checked and, if necessary, reprogrammed.

The victory of the losers, or the story of the creation of FLASH memory (part1)

It would seem that in common between a mobile phone, a GPS navigator, a digital camera and a modern voice recorder. The first thought that comes is that these are digital devices that appeared on the market in the 90s of the last century. But this is only at first glance, if you dig deeper, then all these devices have one thing in common – they use Flash (flash) memory to store data. Flash memory, as a new storage device, has been rapidly developing since 1984. In this article, we will try to highlight the history of the creation and development of Flash memory. Continue reading
