PROBLEM TO BE SOLVED: To reduce the complexity and occupancy area of wirings in a driver circuit for word lines of a memory matrix. SOLUTION: In the electronic driver circuit for the word lines WL in the memory matrix 3, a driver source 2, for example, coded output sides IV0-IV3 of a current/voltage source are connected to selected word lines WLi-2-WLi+1. In this case, the word lines WL are selected for every block by control signals SLNP, SLN1, SLN2, and the outputs of the driver source 2 are applied to them. In that case, each activated word line WLi is selected by the coding of the driver source 2.
