Table 23. Write AC Characteristics, Chip Enable Controlled
Note: 1. Sampled only, not 100% tested.
2. tWHEL has the values shown when reading in the targeted bank. System designers should take this into account and may insert a
software No-Op instruction to delay the first read in the same bank after issuing a command. If it is a Read Array operation in a
different bank tWHEL is 0ns.
