IPC: G06F12/16
Filed: 1986-08-04
Abstract: PURPOSE:To perform a memory access at a high speed by preserving the address of the corresponding memory when a hard error is autonomously detected and therefore avoiding repetition of subsequent processes for detection of hard errors. CONSTITUTION:The errors of the data read out of a memory 52 are checked by an error detecting/correcting part 56. If a data error is detected, the read data corrected by the part 56 is written again to the address held by a retry control part 54 via this control part 54.
