example 1
[0134] Figure 7 Shown is a storage array of a 3D memory, the storage array includes a plurality of memory cells, the gates of the plurality of storage cells are connected to word lines (WL); the storage array also includes a serial selection transistor ( StringSelection Transistor, SST), the serial selection line (String Selection Line, SSL) to which the gate of the SST is connected. The storage array further includes: a ground selection transistor (Ground Selection Transistor, GST) located at the lowest end of the storage array for grounding; the gate of the GST is connected to a ground selection line (Ground Selection Line, GSL). Figure 7 It also shows a common source line (Common Source Line, CSL) of the storage array, and the CSL is connected to the source of the bottommost GST. When the memory array is in the working state, generally the SST and the GST are in the conduction state, so that the voltage injected from the drain of the transistor at the top can be conducte...
