Chapter 7: Functional Description—High-Performance Controller II
The activate to read or write a timing parameter.
The range of legal values is 2-11 cycles.
The activate to activate a timing parameter. The
range of legal values is 2-8 cycles.
The precharge to activate a timing parameter. The
range of legal values is 2-11 cycles.
The mode register load time parameter. This
value is not used by the controller, as the
controller derives the correct value from the
memory type setting.
The activate to precharge a timing parameter. The
range of legal values is 4-29 cycles.
The activate to activate a timing parameter. The
range of legal values is 8-40 cycles.
The write to read a timing parameter. The range
of legal values is 1-10 cycles.
The read to precharge a timing parameter. The
range of legal values is 2-8 cycles.
The four-activate window timing parameter. The
range of legal values is 6-32 cycles.
Reserved for future use.
The refresh interval timing parameter. The range
of legal values is 780-6240 cycles.
The refresh cycle timing parameter. The range of
legal values is 12-88 cycles.
Reserved for future use.
