Abstract
In one embodiment, a controller can perform a secure clear of a poisoned indicator associated with an uncorrectable error (after recovery from the error). To this end, the controller may access a register storing an address of a memory location associated with indicator, determine whether the address corresponds to an entry in a table storing a list of such errors, and perform the clear based at least in part on the determination. Other embodiments are described and claimed.
