Title: Prevention system for destruction in common-use memory pool
Inventor: AKIYAMA TAKASHI
IPC: G06F12/14
Filed: 1989-07-20
Abstract: PURPOSE:To prevent a memory cell from being destroyed owing to the illegal use of the memory cell by enabling access right to be defined in individual memory cell units, comparing the access right with the access right that the program at an access origin has if the memory cell is accessed, and generating an address fault when the access is impossible. CONSTITUTION:When a different program 11 executes an instruction for updating a memory cell 2, an address converting mechanism 6 converts a virtual space address into a real space address by using an address conversion table 5 and compares the program key 9 of a program 11 in a program key register with access keys 4 in an access key table 3. The bit positions of the value '1' of the access key 4 are not all '1' of the program key 9 as a result of the key comparison, so the address converting mechanism 6 finishes the instruction abnormally as the address fault. Consequently, the memory cell is prevented from being destroyed.
