THE DYNAMIC MEMORY SHORTENED OPERATION CYCLE TIME

摘要

The WD driver is utilized to drive output RD of a DB sense amplifier so that the time necessary to amplify selected bit line is reduced. The dynamic memory has additional transisters (M7,M8) over conventional dynamic memory. The transister (M7) is connected between an output stage of sense amplifier (5) and input stage of a WD driver (10) and the transister (M8) is connected between a WD driver (10) and WD line. The RD line data is fed back to a WD driver (10) through the transister (M7) when a reading cycle initiated and as a result the WD driver (10) drives a pair of bit lines with the reduced time.
