ODT(On Die Termination)
On Die Termination (ODT), is a feature that allows a DRAM to turn on/off termination resistance for each DQ, DQS,
/DQS, RDQS, /RDQS, and DM signal for
×
4
×
8 configurations via the ODT control pin. For
×
16 configuration ODT
is applied to each DQ, UDQS, /UDQS, LDQS, /LDQS, UDM, and LDM signal via the ODT control pin. The ODT
feature is designed to improve signal integrity of the memory channel by allowing the DRAM controller to
independently turn on/off termination resistance for any or all DRAM devices.
The ODT function is turned off and not supported in self-refresh mode.
Switch sw1 or sw2 is enabled by ODT pin.
Selection between sw1 or sw2 is determined by Rtt (nominal) in EMRS
Termination included on all DQs, DM, DQS, /DQS, RDQS and /RDQS pins.
Target Rtt (
) = (Rval1) / 2 or (Rval2) / 2
