Fast Page Mode Cycle (Read, Early Write, Read-Write, Read-Modify-Write Cycle)
(Note 24)
Note 24: All previously specified timing requirements and switching characteristics are applicable to their respective Fast page mode cycle.
Note
25:
t
RAS(min)
is specified as two cycles of CAS input are performed.
Note
26:
t
CP(max
) is specified as a reference point only.
Fast page mode read/write cycle time
Fast page mode read write/read modify write cycle time
(Note 25)
(Note 26)
RAS low pulse width for read or write cycle
CAS high pulse width
RAS hold time after CAS precharge
Delay time, CAS precharge to W low
