Estimating the term…
In a case where a data missing area has occurred when a memory portion in a SYNC information set buffer memory is being overwritten with SYNC information sets (error correction data), an initialization DMA unit obtains the starting address and the end address in the data missing area from an address setting DMA device, and writes a specific value indicating that main data contains errors at each address in the data missing area between the starting address and the end address for initialization of the data missing area. Therefore, even in the case of the occurrence of the data missing area in the memory in which the error correction data indicating the presence/absence of errors in the main data is written over existing data and stored, the errors in the main data are corrected properly in accordance with data output from the memory.
A memory initialization device comprising:
A memory initialization method for initializing a memory in which existing data is successively overwritten with error correction data for use in determining whether or not main data contains errors for storage of the error correction data, the method comprising:
