5.5.3. ECC Error Counters Register
This per-pseudo-channel register counts the number of single-bit errors and double-bit errors detected by the HBM controller.
These counts can be used by software to track the reliability of the memory device. To read the ECC error counters register, issue a read command to the offset 32’h0560 for pseudo-channel 0 and 32’h0860 for pseudo-channel 1.
Bits | Access | Default | Name | Description |
---|---|---|---|---|
14:0 | RW1C | 15’h0 | SBE_ERRCNT | Number of correctable single-bit errors in pseudo-channel read responses detected by the HBM controller, since power up or counter reset. This counter saturates at maximum count. Any error after maximum count sets the overflow bit. |
15 | RW1C | 1’b0 | Reserved | Reserved. |
30:16 | RW1C | 15’h0 | DBE_ERRCNT | Number of uncorrectable (double-bit) errors in pseudo-channel read responses detected by the HBM controller, since power up or counter reset. This counter saturates at maximum count. Any error after maximum count sets the overflow bit. |
31 | RW1C | 1’b0 | Reserved | Reserved. |
