q W to R Command Delay
The Write-to-Read (tWRD) command delay is the amount of cycles required
between a valid write command and the next read command. A lower cycle
time results in better performance but is can instability. Adjustable from 0 to
6 cycles.
q W to W Timing
The Write-to-Write (tWRWR) timing is the number of clock cycles between
the last write and the subsequent Write command to the same physical bank.
Adjustable from 2 to 15 cycles.
q CAS Latency
The CAS Latency (tCL) is the time (in number of clock cycles) that elapses
after the memory controller sends a request to read a memory location and
before the data is sent to the module's output pins. The value shown cannot
be changed.
q Clock Drive Strength
This value is filled in by the system and can not be changed by the user.
q Command Per Clock
The Command Per Clock (tCPC) sets the Command Rate for the memory
controller. The value shown cannot be changed
q Async Latency
This value is filled in by the system and can not be changed by the user.
