Notes: • Use either of CE1 or CE2, or both for disenable control of the device.
• Because turning the power-on from an intermediate level cause malfunction, when the power
is turned on, VCC is required to be started from 0 V.
• If the device does not operate within the specified conditions of read cycle, write cycle, power
on/off sequence, memory data can not be guaranteed.
