Semiconductor memory devices including subword driver and layouts thereof

Abstract:

In some examples, a subword driver block of a memory device includes a plurality of active regions of a first type and a plurality of active regions of a second type adjacent to the plurality of active regions of the first type. The subword driver block further includes a plurality of first gate electrodes overlapping with the plurality of active regions of the first type to form a plurality of first transistors, and a plurality of second gate electrodes overlapping with the plurality of active regions of the first type to form a plurality of second transistors. Each of the second transistors is shared by a first subword driver and a second subword driver. Each of the second transistors may include a drain and a source respectively coupled to a first and second word line, which are driven by the first subword driver and the second subword driver, respectively.
