The challenge was to reduce the number of transistors. The schematic from ... The next step was to build a S-R latch using the NAND gates and inverters, which holds some basic memory.

Until recently, NAND flash memory cells were arranged in a planar configuration, using floating gate transistors for their memory operation. A floating gate transistor consists of two gates: a ...

However, Samsung's new V-NAND dispenses with floating gate transistors and uses a different ... composed of silicon nitride (SiN), instead of using a floating gate to prevent interference between ...

However, using techniques borrowed from phase ... pathways modified to carry heat to the floating gate, the portion of the NAND transistor that is filled and drained to denote a 0 or a 1.

This 3D monolithic integration is crucial for increasing transistor density. To demonstrate the potential of this technology, the researchers devised a novel 3D NAND logic gate. Using just four ...

Such memory density is comparable to 48-layer 3D NAND using a popular gate-all ... of arrays of vertically arranged single-gate flat-cell thin film transistors with an ultra thin body, which ...

Each transistor has two gates: a control gate and a floating gate ... Multi-Level Cell (MLC): Each memory cell stores two or more bits of data by using multiple voltage levels. MLC NAND Flash allows ...

The 2D transistors we've been using for half a century. This shows 32nm transistors with the source, drain and channel (the latter covered by the gate ... gen 332-layer NAND chip is 'only ...
