  • Patent number: 11950412
    Abstract: A memory device is described. Generally, the device includes a string of memory transistors, a source select transistor coupled to a first end of the string of memory transistor and a drain select transistor coupled to a second end of the string of memory transistor. Each memory transistor includes a gate electrode formed adjacent to a charge trapping layer and there is neither a source nor a drain junction between adjacent pairs of memory transistors or between the memory transistors and source select transistor or drain select transistor. In one embodiment, the memory transistors are spaced apart from adjacent memory transistors and the source select transistor and drain select transistor, such that channels are formed therebetween based on a gate fringing effect associated with the memory transistors. Other embodiments are also described.

    Abstract: A data storage device includes a non-volatile memory device, which includes a memory cell array including a plurality of memory cells and a control circuit. Each of the memory cells includes a channel layer, a charge trap layer on the channel layer, and a control electrode on the charge trap layer, the charge trap layer being shared by the memory cells. The charge trap layer includes program regions respectively disposed below the control electrodes of the memory cells, and charge spread blocking regions, each of which is disposed between two adjacent ones of the program regions and between two adjacent ones of the control electrodes. The control circuit controls the memory cell array so that a potential barrier is generated in the charge spread blocking regions by charging the charge spread blocking regions with charges having the same polarity as that of program charges stored in the program regions.
