PURPOSE:To provide useful functions such as data protection or the like flexibly by units smaller compared with pages and segments without remarkably marring efficiency. CONSTITUTION:In addition to a conventional data word array 1, this system is provided with an auxiliary storage bit array 2 and control part 6, and is accomplished by interrupting the execution of a program and calling a prescribed procedure corresponding to the value of auxiliary storage bits when data words are red or reloaded. Thus, since process interruption at the time of read or reload can be specified for respective data words by the value of the auxiliary storage bits, various procedures can be applied by the units smaller compared with the pages or the segments, and the usuful functions such as data protection or the like can be realized flexibly. |
