256Mb, 3V Multiple I/O Serial Flash Memory  
Extended Address Register  
Extended Address Register  
The 3-byte address mode can only access 128Mb of memory. To access the full device in  
3-byte address mode, the device includes an extended address register that indirectly  
provides a fourth address byte A[31:25]. The extended address register bit A0 operates as  
memory address bit A24 to select one of the two 128Mb segments of the memory array.  
If 4-byte addressing is enabled, the extended address register settings are ignored.

1 = Highest 128Mb segment  
0 = Lowest 128Mb segment (default)  
Enables specified 128Mb memory segment. The de-  
fault (lowest) setting can be changed to the high-  
est 128Mb segment using bit 1 of the nonvolatile  
configuration register.

The PROGRAM and ERASE operations act upon the 128Mb segment selected in the ex-  
tended address register. The BULK ERASE operation erases the entire device.  
The READ operation begins reading in the selected 128Mb segment, but is not bound  
by it.  
In a continuous READ, when the last byte of the segment is read, the next byte output is  
the first byte of the next segment. The operation wraps to 0000000h; therefore, a down-  
load of the whole array is possible with one READ operation.  
The value of the extended address register does not change when a READ operation  
crosses the selected 128Mb boundary.
