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 ...

首先考虑NMOS部分，如果其中一个NMOS门是高电平，输出必须保持低电平。如下图所示。 其次， PMOS部分，如果A为高，B为高，或者A、B均为高时，PMOS部分必须处于关断的状态。而且，如果A和B均为低时，PMOS部分必须为ON的状态。 如下图所示，即满足以上的要求。

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

NAND Flash is a type of non-volatile memory technology that has revolutionized data storage in the digital age. It is a form of flash memory, which means it can be electrically erased and reprogrammed ...
