Abstract
PURPOSE: To prevent occurrence of the undesired error at the moment when the reading access is given by generating the incorporation enable signal after carrying out the autonomous initial resetting and the reading check at the side of the memory device.
CONSTITUTION: The power source ON is informed from control part 17-0 to memory access control part 13-0 via the ON of power input signal POW, and as a result an autonomous starting is given to read/write access circuit 6-0 to perform the initial setting of memory unit 5. After this, part 13-0 gives an autonomous starting again to circuit 6-0, and then unit 5-0 perform reading in the order of the addresses. At the same time, error check circuit 7-0 generates the syndrome to carry out the error detection and correction for each reading data. And then the structure control register is set, and the incorporation enable signal is supplied to the memory control unit from AND circuit 21-0.
