CIRCUIT STRUCTURE FOR CORRECTING DIFFERENT VOLTAGE IN EACH LINE SECTION IN SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a simple circuit structure which corrects different voltages between respective line sections in a semiconductor integrated circuit, especially a circuit structure which corrects difference between the bit line voltage of a high level and the plate line voltage of a high level of a ferroelectric RAM memory and in which the different voltages (write voltage and read voltage in particular) are corrected with a standard operation and can mutually independently be decided in a test mode. SOLUTION: A voltage correction transistor is provided between a bit line and a plate line in order to solve the above problem.
