Hardware Sequence Flags
Notes:
1. Performing successive read operations from the erase-suspended sector will cause D2 to toggle.
2. Performing successive read operations from any address will cause D6 to toggle.
3. Reading the byte address being programmed while in the erase-suspend program mode will indicate logic “1” at the D2 bit.
However, successive reads from the erase-suspended sector will cause D2 to toggle.
BUSY# (RY/BY#—Ready/Busy)
The BUSY# signal indicates to the host the status of
operations within the Miniature Card. The BUSY#
signal is tied to the components’ RY/BY# pins.
The RY/BY# signal from AMD Flash devices in
the Miniature Card indicate that the Embedded Algo-
rithms are either in progress or have been completed.
If the output is low, the device is busy with either a
program or erase operation. If the output is high, the
device is ready to accept any read/write or erase op-
eration. When the RY/BY# pin is low, the device will
not accept any additional program or erase com-
mands with the exception of the Erase Suspend com-
mand. If a Flash device is placed in an Erase
Suspend mode, the RY/BY# output will be high. Refer
to the section “Sector Erase Suspend” for more infor-
mation.
WORD-WIDE PROGRAMMING
The Word-Wide Programming sequence will be as
usual per Table 5. The Program word command is
A0A0H. Each byte is independently programmed. For
example, if the high byte of the word indicates
the successful completion of programming via one of
its write status bits such as D15, software polling
should continue to monitor the low byte for write com-
pletion and data verification, or vice versa. During the
Embedded Programming operations the device exe-
cutes programming pulses in 9
μ
s increments.
WORD-WIDE SECTOR ERASING
The Word-Wide Sector Erasing of a memory device
pair is similar to word-wide programming. The erase
word command is a six-bus-cycle command sequence
(see Table 5). Each sector is independently erased and
verified. Word-wide erasure reduces total erase time
when compared to byte erasure. Each Flash memory
device in the card may erase at different rates. There-
fore, each device (byte) must be verified separately.
