Both inputs of the NAND gate are tied together, so they will always share the same logic value. As you can see both inputs are connected to VCC, which is 5V, through a 10MΩ resistor which serves as a pull-up resistor, so the inputs into the NAND gate are at a logic level of ...
19 Since no 12-input gate was available, he decided to compose the function from an 8-input and a 4-input nor gate, but mistakenly instantiated a nand gate during schematic entry. A simulation involving these four bits would have exposed the problem, but no such check was undertaken ...
Shielded-bit line(SBL), cells in even BL first, cells in odd BL next (BL-coupling exists) Block/Page Schematic Floating Gate vs SONOS(Charge Trap, CT) FG一旦发生漏电,所有的电荷都会跑光,CT则不会,因为CT存储电荷的介质为绝缘体 CT tunnel oxide可以做的更薄→提高集成度 Summary 文章内容很丰富,...
This work presents an128Gb2bit/cell NANDflash device based on thefirst generation of the V-NAND cell array tech-nology with damascened metal-gate SONOS-type cell[3]. Fig.4shows the die micrograph of the3-D V-NANDflash. This chip has24stacked WL layers and consists of two planes...
The final schematic of our proposed NAND gate structure is shown in Fig. 5. From Bias port, bias optical waves enter the structure and the output state of the NAND gate will be controlled via A and B ports. Logic NAND gate is OFF when both of its logic inputs – A and B – are ...
