The sense amplifiers are grouped, in each row, into sense amplifier blocks. The write-only column selection lines consist of first selection lines for selecting sense amplifier blocks that are in the row that involves the memory cell to be accessed for data write and second selection lines for selecting sense amplifiers that are contained in the selected sense amplifier blocks. The local drivers apply a selection signal to the second selection lines according to a selection signal from the first selection lines. The write-only column selection lines are controlled by signals that are used to control the sense amplifiers.

An analog signal AOUT is outputted from an analog signal generating section 3 in which an adjustment signal AD is inputted. The analog signal AOUT is inputted to a judgment section 1, in which it is compared and judged with a predetermined value and then a judgment signal JG is outputted. The judgment signal JG acts on a predetermined signal storing section 4 as an internal signal and the adjustment signal AD is fetched into the predetermined signal storing section 4. Further, the judgment signal JG is outputted as digital signal through an external terminal T2 and an external tester device acquires the adjustment signal and stores the acquired adjustment signal in the predetermined signal storing section 4. Consequently, the analog signal can be adjusted as analog value without being outputted outside and an adjustment test can be carried out with a simple tester device and according to a simple test method accurately and rapidly.

    摘要: During a read operation, data read from memory cells onto bit lines are amplified simultaneously by sense amplifiers and outputted to the exterior of a memory. In this operation, a data control circuit outputs to the exterior all the data read from the memory cells onto the bit lines and amplified simultaneously by the sense amplifiers. During a write operation, data supplied from the exterior to the bit lines are amplified by the sense amplifiers and written into the memory cells. In this operation, the data control circuit writes into the memory cells all the data inputted from the exterior and amplified simultaneously by the sense amplifiers. Since all the data amplified simultaneously by the sense amplifiers are inputted/outputted from/to the exterior, the data transfer rate of the input/output data can be improved and the power consumption per unit amount of transferred data can be reduced.
