Embedded Program Algorithm
Reset Command
The device automatically powers up in the read/reset
state. A command sequence is not required to read
data in this case. Standard microprocessor cycles re-
trieve array data. This default state ensures that no
spurious alteration of the memory content occurs dur-
ing the power transition. Refer to the AC Characteris-
tics section for the specific timing parameters.
The reset operation is initiated by writing the read/reset
command sequence into the command register. Micro-
processor read cycles retrieve array data from the
memory. The device remains enabled for reads until
the command register contents are altered.
Sector Erase Suspend
Sector Erase Suspend command allows the user to in-
terrupt the chip and then do data reads (not program)
from a non-busy sector while it is in the middle of a Sec-
tor Erase operation (which may take up to several sec-
onds). This command is applicable ONLY during the
Sector Erase operation and will be ignored if written
during the chip Erase or Programming operation. The
Erase Suspend command (B0h) will be allowed only
during the Sector Erase Operation that will include the
sector erase time-out period after the Sector Erase
commands (30h). Writing this command during the
time-out will result in immediate termination of the
time-out period. Any subsequent writes of the Sector
Erase command will be ignored as such, but instead
will be taken as the Erase Resume command. Note
that any other commands during the time out will reset
the device to read mode. The addresses are
don’t-cares in writing the Erase Suspend or Erase Re-
sume commands.
When the Sector Erase Suspend command is written
during a Sector Erase operation, the chip will take be-
tween 0.1
μ
s to 10
μ
s to suspend the erase operation
and go into erase suspended read mode (pseudo-read
mode), during which the user can read from a sector
that is NOT being erased. A read from a sector being
erased may result in invalid data. The user must moni-
tor D6 to determine if the chip has entered the pseu-
do-read mode, at which time D6 stops toggling. Note
that the user must keep track of what state the chip is
in since there is no external indication of whether the
chip is in pseudo-read mode or actual read mode. After
the user writes the Sector Erase Suspend command
and waits until D6 stops toggling, data reads from the
device may then be performed. Any further writes of
the Sector Erase Suspend command at this time will be
ignored.
To resume the operation of Sector Erase, the Resume
command (30H) should be written. Any further writes of
the Resume command at this point will be ignore.
Another Sector Erase Suspend command can be
written after the chip has resumed.
Write Operation Status
Table 15 shows the status bit states for device program
and erase operations.
Data
Polling—D7 (D15 on Odd Byte)
The AMD Flash Miniature Card features Data Polling
as a method to indicate to the host system that the
Embedded algorithms are either in progress or com-
pleted (The host may alternatively monitor BUSY#
(RY/BY#).
While the Embedded Programming algorithm is in oper-
ation, an attempt to read the device will produce the
complement of expected valid data on D7 of the
addressed memory sector or memory device. Upon
completion of the Embedded Program algorithm an
