ABSTRACT:
A voltage divider is placed between a supply terminal and ground and an intermediate node is connected to the word line to ensure a precharging voltage to the word line which is lower than the supply voltage. The voltage divider is characterized by a precharging transistor included in the voltage divider which has electrical and geometrical characteristics similar to those of the memory cells in such a manner as to adapt the precharging voltage to the characteristics of the cells.
