trCd
When drAM is refreshed, both rows and columns are addressed separately.
this setup item allows you to determine the timing of the transition from rAS
(row address strobe) to CAS (column address strobe). the less the clock cy-
cles, the faster the drAM performance.
trP
this setting controls the number of cycles for row Address Strobe (rAS) to be
allowed to precharge. if insufficient time is allowed for the rAS to accumulate
its charge before drAM refresh, refreshing may be incomplete and drAM may
fail to retain data. this item applies only when synchronous drAM is installed
in the system.
trAS
this setting determines the time rAS takes to read from and write to memory
cell.
trFC
this setting determines the time rFC takes to read from and write to a memory
cell.
tWr
Minimum time interval between end of write data burst and the start of a pre-
charge command. Allows sense amplifiers to restore data to cells.
tWtr
Minimum time interval between the end of write data burst and the start of a
column-read command. it allows i/o gating to overdrive sense amplifiers before
read command starts.
trrd
Specifies the active-to-active delay of different banks.
trtP
time interval between a read and a precharge command.
tFAW
this item is used to set the tFAW (four activate window delay) timing.
tWCL
this item is used to set the tWCL (Write CAS Latency) timing.
tCke
this item is used to set the Pulse Width for drAM module.
trtL
this item is used to set round trip Latency settings.
Advanced Channel / 2 timing Configuration
