WebA wordline is a horizontal strip of polysilicon, a hyper-pure form of silicon, and it connects the to the transistor’s (cell’s) control gate. A bitline is connected to a cell’s drain. … WebThe global bitlines of the first series can alternate with the global bitlines of the second series. There can be memory cell material directly between the wordlines and the vertical local bitlines. The memory cell material may form a plurality of memory cells uniquely addressed by wordline/global bitline combinations.
