The following figure shows the HBM Reliability Options tab.
Figure 1. HBM Reliability Options Tab
ECC Options
- Enable ECC Correction
- Automatically generate and store ECC data with all writes and check during readback.
- Enable ECC Scrubbing
- Enabling this option periodically scrubs the selected address range is to correct and rewrite any 1-bit ECC errors detected.
- Initialize Memory Using ECC (Zeroization of Memory)
- When enabled, initializes memory with valid ECC values.
- Scrub Start/End Address for PC0/PC1
- Used to define the address range for which the on-the-fly scrubbing of detected ECC errors occurs. Addresses are defined per pseudo channel, and they are relative to the base address of the given pseudo channel.
- Scrub Interval(hrs) for PC0/PC1
- Time interval, in hours, between memory range scrubs. The default frequency is one time every 24 hours.
- Write data mask
- Write data mask is available when you disable ECC.
Note: While ECC correction can be enabled without
initializing, you must ensure that no reads issue to an address that has not been
written to first.
Parity options
- Command Parity
- Enable parity checks for the command bus.
- Write Data Parity
- Enable parity checks for the write data.
- Read Data Parity
- Enable parity checks for read data.
DBI Options
- Read DBI
- Enable Dynamic Bus Inversion for read data.
- Write DBI
- Enable Dynamic Bus Inversion for write data.
