operation. During Program or Erase operations
Ready/Busy is Low, V
pedance during Read mode, Auto Select mode
and Erase Suspend mode.
After a Hardware Reset, Bus Read and Bus Write
operations cannot begin until Ready/Busy be-
comes high-impedance. See
16., Reset/Block Temporary Unprotect AC Wave-
forms.
The use of an open-drain output allows the Ready/
Busy pins from several memories to be connected
to a single pull-up resistor. A Low will then indicate
that one, or more, of the memories is busy.

power down and power surges. If the Program/
Erase Controller is programming or erasing during
this time then the operation aborts and the memo-
ry contents being altered will be invalid.
A 0.1µF capacitor should be connected between
the V
pin to decouple the current surges from the power
supply. The PCB track widths must be sufficient to
