Read Weight (RDW):
This value is input to the filter if in a given clock there is a
valid read command being issued to the rank.
Write Weight (WRTW):
This value is input to the filter if in a given clock there is a
valid write command being issued to the rank.
Precharge All Weight (PREAW):
BIOS Requirement: When operating with 2N command
rates, the scale for this field is twice that of the read,
write, or idle commands. For example, if a read command
had a weight of 02h, to program a precharge of the same
weight, the value 01h would be entered in this field. BIOS
must never allow a value greater than 7Fh in this field
when in 2N operation.
Precharge Weight (PRECW):
BIOS Requirement: When operating with 2N command
rates, the scale for this field is twice that of the read,
write, or idle commands. For example, if a read command
had a weight of 02h, to program a precharge of the same
weight, the value 01h would be entered in this field. BIOS
must never allow a value greater than 7Fh in this field
when in 2N operation.
Activate Weight (ACTW):
BIOS Requirement: When operating with 2N command
rates, the scale for this field is twice that of the read,
write, or idle commands. For example, if a read command
had a weight of 02h, to program a precharge of the same
weight, the value 01h would be entered in this field. BIOS
must never allow a value greater than 7Fh in this field
when in 2N operation.
Refresh Weight (REFRW):
BIOS Requirement: When operating with 2N command
rates, the scale for this field is twice that of the read,
write, or idle commands. For example, if a read command
had a weight of 02h, to program a precharge of the same
weight, the value 01h would be entered in this field. BIOS
must never allow a value greater than 7Fh in this field
when in 2N operation.
