“My new flash drive has an insane capacity! How does NAND work anyways?”, I was asked by a friend yesterday. So I blacked out and when I came to I remembered ending my reply with “and ya, I think something like that”. No, it wasn’t that bad but clearly I needed to brush ...
How does DRAM work? Memory is made ofbitsof data or program code that are arranged in a two-dimensional grid. DRAM will store bits of data in what's called a storage or memory cell, consisting of a capacitor and a transistor. The storage cells are typically organized in a rectangular co...
It is true that NAND flash has a definite service life. However, flash chips' ability to withstand only thousands of write cycles is never a compelling argument to prove that an SSD has a short service life. This view is incorrect because data is written to an SSD, not to a single chip...
The Greek letter omega (Ω) – the symbol forohm-- can also represent resistance. An ohmmeter can be used to measure resistance. However, low resistance levels cannot be measured accurately by simple ohmmeters. This is because the resistance of the test leads impact the measurement. Four-termi...
‘How Does An SSD Work’ is the fourth article in our series entitled ‘Learning To Run With Flash’. In this series, we take the time to try to explain the ins and outs of SSDs to you the reader, as well as doing our best to provide an understanding of how this amazing technology...
There are variations of the basic gates known as NAND, NOR, and XNOR. These are simply the standard versions with their outputs inverted. Just for some extra context, an AND gate, like all logic gates, can be built using transistors. The image below shows an example of how an AND gate...
(ssd). how does intel® optane™ memory work? intel® optane™ memory uses three-dimensional (3d) xpoint technology to store data, which is a new type of non-volatile memory that's faster than traditional not and (nand) flash memory. it works by storing frequently used data on ...
How Solid-state Drives Work An SSD is composed of NAND flash chips, also known as NAND flash dies, with each die being broken down into smaller elements called blocks, which are made up of pages. However, flash blocks don’t support random overwrites. Once a page is written with data,...

A good value for the resistor is 330 ohms, although anything between 200 and 500 ohms will work fine. LEDs, being diodes, have a polarity, so if your LED does not light, try reversing the leads and see if that helps. It might seem like we've had to go to a tremendous amount of ...
