MX29L1611G / MX29L1611*
The device remains enabled for read status register
mode until the CIR contents are altered by a valid
command sequence.
ABORT MODE
To activate Abort mode, a three-bus cycle operation is
required. The E0H command (Refer to table 3) only stops
Page program or Sector /Chip erase operation currently
in progress and puts the device in Abort mode. So the
program or erase operation will not be completed. Since
the data in some page/sectors is no longer valid due to
an incomplete program or erase operation, the program
fail (Q4) or erase fail (Q5)bit will be set.
A read array command MUST be written to bring the
device out of the abort state without incurring any wake
up latency. Note that once device is brought out, Clear
status register mode is required before a program or
erase operation can be executed.
SECTOR PROTECTION
To activate this mode, a six-bus cycle operation and
VPP=11V are required. There are two 'unlock' write
cycles. These are followed by writing the 'set-up'
command. Two more 'unlock' write cycles are then
followed by the Lock Sector command - 20H. Sector
address is latched on the falling edge of CE of the sixth
cycle of the command sequence. The automatic Lock
operation begins on the rising edge of the last CE pulse
in the command sequence and terminates when the
Status on Q7 is '1' at which time the device stays at the
read status register mode.
The device remains enabled for read status register
mode until the CIR contents are altered by a valid
command sequence (Refer to table 3,6 and Figure 9,11).
VERIFY SECTOR PROTECT
To verify the Protect status of the Top and the Bottom
sector, operation is initiated by writing Silicon ID read
command into the command register. Following the
command write, a read cycle from address XX00H
retrieves the Manufacturer code of C2H. A read cycle
from XX01H returns the Device code F8H. A read cycle
from appropriate address returns information as to which
sectors are protected. To terminate the operation, it is
necessary to write the read/reset command sequence
into the CIR.
(Refer to table 3,4 and Figure 11)
A few retries are required if Protect status can not be
verified successfully after each operation.
SECTOR UNPROTECT
It is also possible to unprotect the sector , same as the
first five write command cycles in activating sector
protection mode followed by the Unprotect Sector
command -40H, the automatic Unprotect operation begins
on the rising edge of the last CE pulse in the command
sequence and terminates when the Status on DQ7 is '1'
at which time the device stays at the read status register
mode.
(Refer to table 3,6 and Figure 10,11)
DATA PROTECTION
The MX29L1611G is designed to offer protection against
accidental erasure or programming caused by spurious
system level signals that may exist during power
transitions. During power up the device automatically
resets the internal state machine in the Read Array mode.
Also, with its control register architecture, alteration of
the memory contents only occurs after successful
completion of specific multi-bus cycle command
sequences.
The device also incorporates several features to prevent
inadvertent write cycles resulting from VCC power-up
and power-down transitions or system noise.
