Abstract
PURPOSE:To simplify the memory eror processing function, by processing only the error that cannot be recovered by a reaccess through a controller that gave an access to a processor or other memories. CONSTITUTION:A main storage controller 26 is initialized by a memory start request signal 34 and monitors an address overerror signal 35 and a protection error signal 36. In case either one of these two signals has an error, the controller 26 carries out an error retry control. When no error exists, a main storage start signal 38 is delivered. Then the contents of an address register 21 and a write data register 22 are sent to the main storage via a buffer 30 when a function register 23 shows the writing action.
