摘要
Some embodiments include apparatuses and methods of forming the apparatuses. One of the apparatuses includes multiple levels of two-transistor (2T) memory cells vertically arranged above a substrate. Each 2T memory cell includes a charge storage transistor having a gate, a write transistor having a gate, a vertically extending access line, and a single bit line pair. The source or drain region of the write transistor is directly coupled to a charge storage structure of the charge storage transistor. The vertically extending access line is coupled to gates of both the charge storage transistor and the write transistor of 2T memory cells in multiple respective levels of the multiple vertically arranged levels. The vertically extending access line and the single bit line pair are used for both write operations and read operations of each of the 2T memory cells to which they are coupled.
