DEFINITION

Classification: 714/5

Of memory or peripheral subsystem:

(under subclass 3) Subject matter further including means or steps for recovery from a fault of a memory function level or the peripheral function level, or for recovery limited to a specialized processor accessing either memory, peripheral, or other I/O device.

(1) Note. "Page faults" are a species of faults peculiar to memory accessing and are classified elsewhere. See the SEE OR SEARCH THIS CLASS, SUBCLASS notes below.

710+, for memory fault recovery of general utility without significant data processing features claimed.

710, Electrical Computers and Digital Processing Systems-Input/Output:,

1+, for transferring data from one or more peripherals to one or more computers for the latter to process, store, or further transfer or for transferring data from the computers to the peripherals (i.e., Input/Output data processing). 711, Electrical Computers and Digital Processing Systems: Memory,

100+, for means (e.g., processor, controller, etc.) or steps for governing memory in a digital data processing system or the passage (e.g., reading or writing) of data thereto and subclasses 133+for entry replacement strategies and page fault recovery.
