PROBLEM TO BE SOLVED: To reduce bit line capacity by cutting down the numbers of bit line contacts in a sense amplifier. SOLUTION: An element pattern of columnar gate and another element pattern of equalizer circuit are formed as a fused element pattern. For example, a transistor having a gate G1 as a component of a columnar gate, another transistor having gate G3 as a component of an equalizer circuit and the other transistor having gate G5 share a diffused layer S2 to be a common node N1. Likewise, common nodes N2, N3 and N4 are commonly owned respectively by one transistor constituting a columnar gate and the other two transistors constituting a bit equalizer. Furthermore, the common nodes N2, N3 and N4 are respectively connected to the bit lines via the bit line contacts. |
