Protection field 2: protection description
Bits 0 - 31 point to the protection register physi-
cal lock word address in the JEDEC plane.
The bytes that follow are factory or user-progam-
mable.
Bits 32 - 39 = n where n equals factory program-
med groups (low byte).
Bits 40 - 47 = n where n equals factory program-
med groups (high byte).
Bits 48 - 55 = n where 2n equals factory program-
med bytes/groups.
Bits 56 - 63 = n where n equals user programmed
groups (low byte).
Bits 64 - 71 = n where n equals user programmed
groups (high byte).
Bits 72 - 79 = n where 2
n
equals user programma-
ble bytes/groups.

hex value represents the
number of read-page bytes. See offset 28h for
device word width to determine page-mode data
output width. 00h indicates no read page buffer.
Number of synchronous mode read configuration
fields that follow. 00h indicates no burst capabili-
ty.
