111 = Upper 128Mb segment
110 = Seventh 128Mb segment
101 = Sixth 128Mb segment
100 = Fifth 128Mb segment
011 = Fourth 128Mb segment
010 = Third 128Mb segment
001 = Second 128Mb segment
000 = Lower 128Mb segment (default)
Description
–
Enable selecting 128Mb segmentation. For A[26:24],
the default setting is determined by bit 1 of the non-
volatile configuration register. However, this setting
can be changed using the WRITE EXTENDED AD-
DRESS REGISTER command.
Note:
1. The extended address register is for an application that supports only 3-byte addressing.
It extends the device's first three address bytes A[23:0] to a fourth address byte A[31:24]
to enable memory access beyond 128Mb. The extended address register bits [2:0] are
used to select one of the eight 128Mb segments of the memory array. If 4-byte address-
ing is enabled, extended address register settings are ignored.
