BADRAM[1:0]: Bad DRAM Marker
This register implements “failed-device” markers for the enhanced demand scrub
algorithm. Hardware “marks” bad devices. The “mark” is a number between 1 and 18
inclusive. A value of “0_0000” indicates an “un-marked” rank: all RAM’s are presumed
“good”. Only ranks containing x4 DRAM are “marked”.
BADCNT[1:0]: Bad DRAM Counter
This register implements “failing-device” counters for the aliased uncorrectable error
identification algorithm. “Count” double-adjacent symbol errors within x8 devices.
“Drip” each counter after “MC.BADRAMTH” patrol scrub cycles through all of memory.
Values of “MC.BADRAMTH” and “0” cannot be “dripped”. A value of “MC.BADRAMTH”
cannot be incremented. “Mark” the BADRAM(A/B) register when a count reaches
“MC.BADRAMTH”.
