Abstract
A device includes a write bit line and a read bit line extending in a first direction, and a write word line and a read word line extending in a second direction perpendicular to the first direction. The device further includes a memory cell including a write transistor and a read transistor. The write transistor includes a first gate connected to the write word line, a first source/drain connected to the write bit line, and a second source/drain connected to a data storage node. The read transistor includes a second gate connected to the data storage node, a third source/drain connected to the read bit line, and a fourth source/drain connected to the read word line.
