Hyper Page Mode Cycle (Read, Early Write, Read -Write, Read-Modify-Write Cycle,
Read Write Mix Cycle,Hi-Z control by /OE or /W) (Note 25)
Note 25: All previously specified timing requirements and switching characteristics are applicable to their respective Hyper page mode cycle.
26: tRAS(min) is specified as two cycles of /CAS input are performed.
27: tCP(max) is specified as a reference point only. If tCP
≥
tCP(max),access time is controlled exclusively by tCAC.
