摘要：
The invention relates to a memory having writable memory cells (MC) as well as a bit line pair (BL, /BL) which links the memory cells (MC) with a differential read amplifier (SA). A control unit (CTR) serves to precharge the bit lines in several stages before a memory cell (MC) is conductively connected to one of the bit lines (BL) during a read access. During a write access the control unit (CTR) carries out no more than a part of the steps provided for a read access and required for precharging the bit lines, before the read amplifier transmits data to the bit line pair (BL, /BL).
