Command Definitions
Table 14.
Am29DL16xD Command Definitions
Legend:
X = Don’t care
RA = Address of the memory location to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses
latch on the falling edge of the WE# or CE# pulse, whichever happens
later.
PD = Data to be programmed at location PA. Data latches on the rising
edge of WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or
erased. Address bits A19–A12 uniquely select any sector.
BA = Address of the bank that is being switched to autoselect mode, is
in bypass mode, or is being erased.
Notes:
1.
2.
See Table 1 for description of bus operations.
All values are in hexadecimal.
3.
Except for the read cycle and the fourth cycle of the autoselect
command sequence, all bus cycles are write cycles.
4.
Data bits DQ15–DQ8 are don’t care in command sequences,
except for RD and PD.
5.
Unless otherwise noted, address bits A19–A11 are don’t cares.
6.
No unlock or command cycles required when bank is reading
array data.
7.
The Reset command is required to return to reading array data
(or to the erase-suspend-read mode if previously in Erase
Suspend) when a bank is in the autoselect mode, or if DQ5 goes
high (while the bank is providing status information).
8.
The fourth cycle of the autoselect command sequence is a read
cycle. The system must provide the bank address to obtain the
manufacturer ID, device ID, or SecSi Sector factory protect
information. Data bits DQ15–DQ8 are don’t care. See the
Autoselect Command Sequence
section
for more information.
The data is 81h for factory locked and 01h for not factory locked.
9.
10. The data is 00h for an unprotected sector/sector block and 01h
for a protected sector/sector block.
11. The Unlock Bypass command is required prior to the Unlock
Bypass Program command.
12. The Unlock Bypass Reset command is required to return to
reading array data when the bank is in the unlock bypass mode.
13. The system may read and program in non-erasing sectors, or
enter the autoselect mode, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase
operation, and requires the bank address.
14. The Erase Resume command is valid only during the Erase
