CAS before RAS Refresh Cycle
(Note 29)
CAS setup time before RAS low
CAS hold time after RAS low
Read setup time before RAS low
Read hold time after RAS low
CAS low pulse width
Note 29 : Eight or more CAS before RAS cycles instead of eight RAS cycles are necessary for proper operation of CAS before RAS refresh mode.
