Answer / meena
A wait state is a delay experienced by a microprocessor
when accessing external memory or another device that is
slow to respond. the vice versa also come into scenario.
Now, to be able to access slow memory the microprocessor
must be able to delay the transfer until the memory access
is complete. One way is to increase the micro processor
clock period by reducing the clock frequency. Some micro
processors provide a special control input called READY to
allow the memory to set its own memory cycle time. If after
sending an address out, the microprocessor does not receive
a READY input from memory, it enters a wait state for as
long as the READY line is in 0 state. When the memory
access is completed the READY goes high to indicate that
the memory is ready for specified transfer.
