External erase verification is not required because data is erased automatically by internal control circuit. Erasure completion can be veri- fied by DATA polling and toggle bit checking after auto- matic erase starts. Device outputs 0 during erasure and 1 after erasure 0n Q7.(Q6 is for toggle bit; see toggle bit, DATA polling, timing waveform) AUTOMATIC CHIP ERASE TIMING WAVEFORM (WORD MODE) tCWC tAS tCEP tDS tDH Vcc 5V CE OE Q0,Q1, Q4(Note 1) WE A11~A15 tCEPH1 tAH Q7 Command In A0~A10 Command In Command In Command In Command In Command In tAETC DATA polling 2AAH 555H 555H Command #AAH Command #55H Command #80H (Q0~Q7) Notes: (1).
