Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...

Spin waves can be applied to low-power multi-input-multi-output logic gates based on its wave functionality realized without electron travelling. In particular, spin waves propagating in yttrium iron ...

Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

What's "bringing excitement back into personal computing" more than anything else? According to Micron, it's SSDs, and it says it's now "accelerating this enthusiasm" with its new RealSSD C400 drives.
