Abstract
A memory device is provided. The memory device comprises a memory cell, a first power rail and a suppressing circuit. The memory cell is coupled to a word line. The first power rail transmits a first supply voltage. The suppressing circuit comprises a first transistor and a second transistor. The first transistor is diode-connected, coupled to the word line, and disposed at a first layer. The second transistor is diode-connected coupled between the first transistor and the first power rail, and disposed at a second layer under the first layer. The first transistor and the second transistor overlap with each other in a layout view.
