    摘要: This disclosure is concerned with NAND flash memory, and proposes a method for programming the NAND flash memory. The NAND flash memory comprises a semiconductor channel layer, a first gate on a first side of the channel layer, and a plurality of second gates on a second side of the channel layer. Each second gate is associated with one memory cell and connected to one word line. The method comprises applying a first voltage to the first gate, and a pass voltage to one or more word lines, to allow charge to inject into the channel layer and form charge packets. Each charge packet is arranged next to one of the second gates. The method further comprises applying a programming voltage to the word lines, to move the charge packets from the channel layer into the memory cells associated with the second gates next to which they are arranged.

    摘要: This disclosure relates to a charge-coupled device (CCD) memory. The CCD memory is 3D integrated. The CCD memory comprises a gate stack with a plurality of gate layers and spacer layers alternatingly arranged one on the other, and with a plurality of semiconductor-based channels extending in the stack. The channels may be formed from a semiconductor oxide material. Further, the CCD memory comprises dielectric layers, wherein each dielectric layer is arranged between one of the channels and at least one of the gate layers. Each channel of the CCD memory forms, in combination with the gate layers and at least one of the dielectric layers, a string of charge storage capacitors, and each string of charge storage capacitors is operable as a CCD register. The CCD memory also comprises a readout layer, which comprises a plurality of readout stages configured to individually readout stored charge from each of the CCD registers.
