Data Retention Waveform
Switching Waveforms
Read Cycle No.1[10, 11]
Read Cycle No. 2 (OE Controlled)[11, 12]
Notes:
9. Full Device operation requires linear VCC ramp from VDR to VCC(min) > 100 ms or stable at Vcc(min) > 100 ms.
10.Device is continuously selected. OE, CE = VIL.
11.W E is HIGH for read cycle.
12.Address valid prior to or coincident with CE transition LOW.
