Semiconductor memory device exhibiting improved high speed and stable write operations

摘要

The present invention provides a circuitry for supplying data from a write input/output line pair to a digit line pair for writing the data into memory cells. The circuitry comprises: a balancing device for balancing in voltage level between the write input/output line pair by making a connection of the write input/output line pair; and a controller connected to the balancing device for controlling balancing operations of the balancing device.
