ABSTRACT:
A magnetic bubble memory system with a write protecting function is disclosed. In a power on reset mode or initiallizing mode of an information handling system including the bubble memory system, a bubble memory controller directs to and stores in its own memory, an information representative of a write protecting range for a bubble memory device, from a hidden memory region of the bubble memory device. The bubble memory controller compares the write protecting range to the information designating the address range of the bubble memory device in which a new information is to be written, in response to the write command from a host central processing unit. As a result of the comparison, if the both address ranges overlap each other, the bubble memory controller will execute the write protection and generate a write protection error message for the host CPU.
