Abstract
PURPOSE: To remedy the steady fault of the memory element in a simple and economical way by giving inversion to each bit of the data read out when the inverse display bit of the data region is on and at the reading time, thus increasing the efficiency for operation of the computer.
CONSTITUTION: Inverse display bit 11 is provided every inversion circuit of the data and data reion 12, and each bit value of the data is written after inversion into region 12 which is incapable of the steady writing. At the same time, inverse display bit 11 of region 12 is turned on previously, and then each bit of the reading data is inverted if bit 11 is on at the reading time. As a result, the steady fault can be remedied for the memory element in a simple and economical way, thus ensuring a high-efficiency operation for the computer.
