• TRRD: Active bankA to Active bankB
Reset value is 2 cycles.
This field defines the delay between an Active command in BankA and an active command in bankB in number of cycles.
Number of cycles is between 1 and 15.
• TWTR: Internal Write to Read Delay
Reset value is 0.
This field is unique to Low-power DDR1-SDRAM devices and DDR2-SDRAM devices.
This field defines the internal write to read command Time in number of cycles. Number of cycles is between 1 and 7.
• REDUCE_WRRD: Reduce Write to Read Delay
Reset value is 0.
This field reduces the delay between write to read access for low-power DDR-SDRAM devices with a latency equal to 2. To
use this feature, TWTR field must be equal to 0. Important to note is that some devices do not support this feature.
• TMRD: Load Mode Register Command to Active or Refresh Command
Reset Value is 2 cycles.
This field defines the delay between a Load mode register command and an active or refresh command in number of
cycles. Number of cycles is between 0 and 15.
