Assessing in-field reliability of computer memories

A system comprising a host computer system:

• to take control of a portion of a computer memory circuit,
• to utilize a portion of a computer memory bus, wherein the portion of the computer memory bus is associated with the portion of the computer memory circuit,
• to move computer memory circuit data stored in the portion of the computer memory circuit to a host computer storage device,
• to execute a set of logical operations assessing reliability of the portion of the computer memory circuit, resulting in assessment data stored in a reliability error monitor (REM) computer storage device,
• to transmit the stored assessment data from the REM computer storage device to a computer memory controller circuit, and
• to move, in response to the transmitting, the moved computer memory circuit data from the host computer storage device back to the portion of the computer memory circuit.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• taking control, by a host computer system, of a portion of a computer memory circuit;
• utilizing, by the host computer system, a portion of a computer memory bus, wherein the portion of the computer memory bus is associated with the portion of the computer memory circuit;
• moving, by the host computer system, computer memory circuit data stored in the portion of the computer memory circuit to a host computer storage device;
• executing, by the host computer system, a set of logical operations assessing reliability of the portion of the computer memory circuit, resulting in assessment data stored in a reliability error monitor (REM) computer storage device;
• transmitting, by the host computer system, the stored assessment data from the REM computer storage device to a computer memory controller circuit;
• and
• in response to the transmitting, moving, by the host computer system, the moved computer memory circuit data from the host computer storage device back to the portion of the computer memory circuit.
