Abstract
Embodiments include method, systems and computer program products for operating a resettable write once read many (RWORM) memory. The method includes receiving, by a processor, a request for at least a portion of memory in a computer system to be designated as RWORM memory. The processor further writes data to the RWORM memory. The processor further maintains the RWORM memory in a read-only state after the RWORM memory is written to. The processor further re-designates the RWORM memory to a read/write state in response to encountering a system reset.
