Write Pulse “Glitch” Protection  
Noise pulses of less than 3 ns (typical) on OE#, CE# or WE# do not initiate a write  
cycle.  
Logical Inhibit  
Write cycles are inhibited by holding any one of OE# = V , CE# = V or WE# =  
IL  
IH  
V . To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a  
IH  
logical one.  
Power-Up Write Inhibit  
If WE# = CE# = V and OE# = V during power up, the device does not accept  
IL  
IH  
commands on the rising edge of WE#. The internal state machine is automatically  
reset to the read mode on power-up.  
Common Flash Memory Interface (CFI)  
The Common Flash Interface (CFI) specification outlines device and host system  
software interrogation handshake, which allows specific vendor-specified soft-  
ware algorithms to be used for entire families of devices. Software support can  
then be device-independent, JEDEC ID-independent, and forward- and back-  
ward-compatible for the specified flash device families. Flash vendors can  
standardize their existing interfaces for long-term compatibility.  
This device enters the CFI Query mode when the system writes the CFI Query  
command, 98h, to address 55h, any time the device is ready to read array data.  
The system can read CFI information at the addresses given in Tables 27-30. To  
terminate reading CFI data, the system must write the reset command.  
The system can also write the CFI query command when the device is in the au-  
toselect mode. The device enters the CFI query mode, and the system can read  
CFI data at the addresses given in Tables 27-30. The system must write the reset  
command to return the device to reading array data.  
For further information, please refer to the CFI Specification and CFI Publication  
100, available via the World Wide Web at http://www.amd.com/flash/cfi. Alter-  
natively, contact your sales representative for copies of these documents.
