| Zusammenfassung: | PURPOSE:To reduce power consumption in a semiconductor storage. CONSTITUTION:Data lines DE, DW* are divided to plural pieces in the direction of prolonging the data lines, and plural memory blocks MARY(1)-MARY (4) are formed. Switches Q3, Q4 for selectively conducting the data lines related to the division to common data lines are provided at every memory block, and a data input buffer DIB for minutely amplifying the writing input data Di by common data lines CD, CD* is provided. Thus, a charge/discharge current is reduced, and further, power consumption is reduced. |
