512Mb, Multiple I/O Serial Flash Memory  
READ MEMORY Operations  
READ MEMORY Operations  
The device supports default reading and writing to an A[MAX:MIN] of A[23:0] (3-byte  
address).  
Reading and writing to an A[MAX:MIN] of A[31:0] (4-byte address) is also supported. Se-  
lection of the 3-byte or 4-byte address range can be enabled in two ways: through the  
nonvolatile configuration register or through the ENABLE 4-BYTE ADDRESS MODE/  
EXIT 4-BYTE ADDRESS MODE commands. Further details for these settings and com-  
mands are in the respective register and command sections of the data sheet.  
After any READ command is executed, the device will output data from the selected ad-  
dress in the die. After a die boundary is reached, the device will start reading again from  
the beginning of the same 256Mb die.  
A complete device reading is completed by executing read twice.  
3-Byte Address  
To execute READ MEMORY commands, S# is driven LOW. The command code is input  
on DQn, followed by input on DQn of three address bytes. Each address bit is latched in  
during the rising edge of the clock. The addressed byte can be at any location, and the  
address automatically increments to the next address after each byte of data is shifted  
out; therefore, a die can be read with a single command. The operation is terminated by  
driving S# HIGH at any time during data output.
