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.

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 ...

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 ...

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 ...

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 ...
