• TXARD: Exit Active Power Down Delay to Read Command in Mode “Fast Exit”.
The Reset Value is 2 cycles.
This field defines the delay between cke set high and a Read Command in number of cycles. Number of cycles is between
0 and 15.
Note: This field is found only in DDR2-SDRAM devices.
• TXARDS: Exit Active Power Down Delay to Read Command in Mode “Slow Exit”.
The Reset Value is 6 cycles.
This field defines the delay between cke set high and a Read Command in number of cycles. Number of cycles is between
0 and 15.
Note: This field is found only in DDR2-SDRAM devices.
• TRPA: Row Precharge All Delay
The Reset Value is 0 cycle.
This field defines the delay between a Precharge ALL banks Command and another command in number of cycles. Num-
ber of cycles is between 0 and 15.
Note: This field is found only in DDR2-SDRAM devices.
• TRTP: Read to Precharge
The Reset Value is 2 cycles.
This field defines the delay between Read Command and a Precharge command in number of cycle.
Number of cycles is between 0 and 7.
• TFAW: Four Active window
The Reset Value is 4 cycles.
DDR2 devices with 8-banks (1Gb or larger) have an additional requirement: t
ACTIVATE commands may be issued in any given t
Number of cycles is between 0 and 15.
Note: This field is found only in DDR-SDRAM 2 devices with eight internal banks
