Power-Off with Hardware Data Protection
The following sections describe the host system interface signal behavior and timing for the 29GL-S family
flash devices.
Table 8.1
Legend:
L = V
H = V
X = either V
L/H = rising edge
H/L = falling edge
Valid = all bus signals have stable L or H level
Modified = valid state different from a previous valid state
Available = read data is internally stored with output driver controlled by OE#
Notes:
1. WE# and OE# can not be at V
2. Read with Output Disable is a read initiated with OE# High.
3. Automatic Sleep is a read/write operation where data has been driven on the bus for an extended period, without CE# going High and the
