Abstract
The invention relates to a method of correction of corrupted data stored in a memory location by scrubbing. The memory is associated with an error correcting code device which corrects the data transmitted to a user requesting them. The method comprises three steps. During a first step, the data is read from the memory at an address contained in a first register, corrected, and stored into a second register. A reservation is created. During a second step, if a reservation exists the data contained in the second register is written back into the same memory location. The reservation is cleared and a particular field of a condition register is modified. If a reservation does not exist, the second step is completed without altering the memory location. During the third step, the status of the condition register is checked. If the test is positive the process is ended, the scrubbing being successful; if not, an iteration of the three above steps is executed.
