Application ID: 05536142

Base Claim:
1. A protective system to prevent data word losses in a random access memory in the presence of a radiation pulse from a nuclear radiation event, or the like, which memory includes a multiplicity of individual memory elements and associated selective and read/write circuitry; the combination of: circumvent circuitry coupled to the selective and read/write circuitry for protecting all unaddressed memory elements in the memory in the event of a radiation pulse; accessing means coupled to the memory for selectively accessing the data words in the memory at the different memory locations therein; and error correction and word recovery logic circuit means coupled to the accessing means for reconstituting the data word being accessed during the radiation pulse so as to replace such data word in the memory with a reconstituted data word.

Claim 4:
4. The combination defined in claim 1, and which includes a circumvention and subsequent word recovery operation of the system.
