Erase Timer Bit (DQ3).
The Erase Timer Bit can
be used to identify the start of Program/Erase
Controller operation during a Block Erase com-
mand.
Once the Program/Erase Controller starts erasing
the Erase Timer Bit is set to ’1’. Before the Pro-
gram/Erase Controller starts the Erase Timer Bit is
set to ’0’ and additional blocks to be erased may
be written to the Command Interface. The Erase
Timer Bit is output on DQ3 when the Status Reg-
ister is read.
Alternative Toggle Bit (DQ2).
The
Toggle Bit can be used to monitor the Program/
Erase controller during Erase operations. The Al-
ternative Toggle Bit is output on DQ2 when the
Status Register is read.
During Chip Erase and Block Eraseoperations the
Toggle Bit changes from ’0’ to ’1’ to ’0’, etc., with
Alternative
successive Bus Read operations from addresses
within theblocks being erased. Once the operation
completes the memory returns to Read mode.
During Erase Suspend the Alternative Toggle Bit
changes from ’0’ to ’1’ to ’0’, etc. with successive
Bus Read operations from addresses within the
blocks being erased. Bus Read operations to ad-
dresses within blocks not being erased will output
the memory cell data as if in Read mode.
After an Erase operation that causes the Error Bit
to be set the Alternative Toggle Bit can be used to
identify which block or blocks have caused the er-
ror. The Alternative Toggle Bit changes from ’0’ to
’1’ to ’0’, etc. with successive Bus Read Opera-
tions from addresses within blocks that have not
erased correctly. The Alternative Toggle Bit does
not change if the addressed block has erased cor-
rectly.
