FIELD: integrated semiconductor circuits of base plate type incorporating storage cells arranged in rows and columns and intended for reading only. SUBSTANCE: these cells are divided into first and second groups including transistors of first and second type of conductance. Semiconductor storage has decoding means with address control of lines and columns meant for selection of output of first or second groups in reply to signal of column selection. EFFECT: improved operational stability and reliability. 4 cl, 2 dwg
