1. Only the third and fourth cycles of the PROGRAM command are represented. The PRO-  
GRAM command is followed by checking of the status register data polling bit and by a  
READ operation that outputs the data (DOUT) programmed by the previous PROGRAM  
command.  
Notes:  
2. PA is the address of the memory location to be programmed. PD is the data to be pro-  
grammed.  
3. DQ7 is the complement of the data bit being programmed to DQ7 (See Data Polling Bit  
[DQ7]).  
4. See the following tables for timing details: Read AC Characteristics, WE#-Controlled  
Write AC Characteristics, and CE#-Controlled Write AC Characteristics.
