CAS LATENCY (READ LATENCY)
The CAS latency is the delay, in clock cycles, between the registration of a READ command and the availability of the first bit of output
data. The latency can be set to 4~11 clocks. If a READ command is registered at clock edge
n
, and the latency is
m
clocks, the data will
be available nominally coincident with clock edge
n
+
m
. Below table indicates the operating frequencies at which each CAS latency set-
ting can be used. Reserved states should not be used as unknown operation or incompatibility with future versions may result.
