The HBM Reliability Options tab is shown in the following figure.
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
- When enabled, the selected address range is periodically scrubbed 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 are relative to the base address of the given pseudo channel.
- Scrub Interval(hrs) for PC0/PC1
- The interval, in hours, at which the memory range is scrubbed. The default frequency is once every 24 hours.
- Write data mask
- Write data mask is available when ECC is disabled.
Note: While ECC correction can be enabled without initialization,
you must ensure that no reads are issued 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.
