The Program/Erase Controller will suspend within
15
μ
s of the Erase Suspend Command being is-
sued. Once the Program/Erase Controller has
stopped the memory willbe set to Read mode and
the Erasewill be suspended. If the Erase Suspend
command is issued during the period when the
memory is waiting for an additional block (before
the Program/Erase Controller starts) then the
Erase is suspended immediately and will start im-
mediately when the Erase Resume Command is
issued. It will not be possible to select any further
blocks for erasure after the Erase Resume.
During Erase Suspend it is possible to Read and
Program cells in blocks that are not being erased;
both Read and Program operations behave as
normal on these blocks. Reading from blocks that
are being erased will output the Status Register. It
is alsopossible to enter theAuto Select mode: the
memory willbehave as inthe Auto Select mode on
all blocks until a Read/Resetcommand returns the
memory to Erase Suspend mode.
Erase Resume Command.
The Erase Resume
command must be used to restart the Program/
Erase Controller from Erase Suspend. An erase
can be suspended and resumed more than once.
STATUS REGISTER
Bus Read operations from any address always
read the Status Register during Program and
Erase operations. It isalso readduring EraseSus-
pend when an address within a block being erased
is accessed.
The bits in the Status Register are summarized in
Table 7, Status Register Bits.
Data Polling Bit (DQ7).
The Data Polling Bit can
be used to identify whether the Program/Erase
Controller has successfully completed its opera-
tion or if it has responded to an Erase Suspend.
The Data Polling Bit is output on DQ7 when the
Status Register is read.
During Program operations the Data Polling Bit
outputs the complement of the bit being pro-
grammed to DQ7. After successful completion of
the Program operation the memory returns to
Read mode and Bus Read operations from the ad-
dress just programmed output DQ7, not its com-
plement.
During Erase operations the Data Polling Bit out-
puts ’0’, the complement of the erased state of
DQ7. After successful completion of the Erase op-
eration the memory returns to Read Mode.
In Erase Suspend mode the Data Polling Bit will
output a ’1’ during a Bus Read operation within a
block being erased. The Data Polling Bit will
change from a ’0’ to a ’1’ when the Program/Erase
Controller has suspended the Erase operation.
Figure 3, Data Polling Flowchart, gives an exam-
ple of how to use the Data Polling Bit. A Valid Ad-
dress is the address being programmed or an
address within the block being erased.
