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.

this time then the operation aborts and the memo-

A 0.1µF capacitor should be connected between
