PURPOSE:To relax noises, and to prevent the deterioration of the sensitivity of a sense amplifier by forming a third conductive layer for relaxing stress by a resin onto a MOS transistor constituting the sense amplifier and grounding the third conductive layer. CONSTITUTION:A second layer Al wiring 13 as a third conductive layer is grounded. In such an example, the second layer Al wiring 13 not only fills the role of a buffer layer relaxing the residual stress of molding but also reduces noises from the outside. Accordingly, noises given to a sense amplifier are relaxed, and stress can also be mitigated. THe deterioration of the sensitivity of a sense amplifier circuit can be inhibited. |
