Read Cycle No. 2 (OE Controlled)[7, 14, 15]
Notes:
12. Full device operation requires linear VCC ramp from VDR to VCC(min.) > 50 µs or stable at VCC(min.) > 50 µs
13. Device is continuously selected. OE, CE = VIL.
14. WE is HIGH for read cycle.
15. Address valid prior to or coincident with CE transition LOW.
