16,777,216-BIT (1,048,576 -WORD BY 16-BIT ) CMOS
3.3V-ONLY FLASH MEMORY &
4,194,304-BIT (524,288-WORD BY 8-BIT) CMOS SRAM
Stacked-MCP (Multi Chip Package)
FUNCTION
The Flash Memory of M6MGB/T162S4BVP includes on-chip
program/erase control circuitry. The Write State Machine (WSM)
controls block erase and byte/page program operations.
Operational modes are selected by the commands written to the
Command User Interface (CUI). The Status Register indicates the
status of the WSM and when the WSM successfully completes the
desired program or block erase operation.
A Deep Powerdown mode is enabled when the F-RP# pin is at
GND, minimizing power consumption.
Read
The Flash Memory of M6MGB/T162S4BVP has three read modes,
which accesses to the memory array, the Device Identifier and the
Status Register. The appropriate read command are required to
be written to the CUI. Upon initial device powerup or after exit
from deep powerdown, the Flash Memory automatically resets to
read array mode. In the read array mode, low level input to F-CE#
and OE#, high level input to WE# and F-RP#, and address signals
to the address inputs ( A19-A0:Word Mode) output the data of the
addressed location to the data input/output ( D15-D0:Word Mode).
Write
Writes to the CUI enables reading of memory array data, device
identifiers and reading and clearing of the Status Register. They
also enable block erase and program. The CUI is written by
bringing WE# to low level, while F-CE# is at low level and OE# is
at high level. Address and data are latched on the earlier rising
edge of WE# and F-CE#. Standard micro-processor write timings
are used.
Deep Power-Down
When F-RP# is at VIL, the device is in the deep powerdown
mode and its power consumption is substantially low. During
read modes, the memory is deselected and the data
input/output are in a high-impedance(High-Z) state. After
return from powerdown, the CUI is reset to Read Array , and
the Status Register is cleared to value 80H.
During block erase or program modes, F-RP# low will abort
either operation. Memory array data of the block being altered
become invalid.
Automatic Power-Saving (APS)
The Automatic Power-Saving minimizes the power
consumption during read mode. The device automatically
turns to this mode when any addresses or F-CE# isn't
changed more than 200ns after the last alternation. The
power consumption becomes the same as the stand-by
mode. While in this mode, the output data is latched and can
be read out. New data is read out correctly when addresses
are changed.
Alternating Background Operation (BGO)
The Flash Memory of M6MGB/T162S4BVP allows to read array
from one bank while the other bank operates in software
command write cycling or the erasing / programming operation in
the background. Read array operation with the other bank in BGO
is performed by changing the bank address without any additional
command. When the bank address points the bank in software
command write cycling or the erasing / programming operation,
the data is read out from the status register. The access time with
BGO is the same as the normal read operation.
Output Disable
When OE# is at VIH, output from the devices is disabled. Data
input/output are in a high-impedance(High-Z) state.
Standby
When F-CE# is at VIH, the device is in the standby mode and
its power consumption is reduced. Data input/output are in a
high-impedance(High-Z) state. If the memory is deselected
during block erase or program, the internal control circuits
remain active and the device consume normal active power
until the operation completes.

SOFTWARE COMMAND DEFINITIONS
The device operations are selected by writing specific software
command into the Command User Interface.
Read Array Command (FFH)
The device is in Read Array mode on initial device power up and
after exit from deep powerdown, or by writing FFH to the
Command User Interface. After starting the internal operation the
device is set to the read status register mode automatically.
Read Device Identifier Command (90H)
It can normally read device identifier codes when Read Device
Identifier Code Command(90H) is written to the command latch.
Following the command write, the manufacturer code and the
device code can be read from address 0000H and 0001H,
respectively.
Read Status Register Command (70H)
The Status Register is read after writing the Read Status Register
command of 70H to the Command User Interface. Also, after
starting the internal operation the device is set to the Read Status
Register mode automatically.
The contents of Status Register are latched on the later falling
edge of OE# or F-CE#. So F-CE# or OE# must be toggled every
status read.
Clear Status Register Command (50H)
The Erase Status, Program Status and Block Status bits are set to
"1"s by the Write State Machine and can only be reset by the Clear
Status Register command of 50H. These bits indicates various
failure conditions.
C)Single Data Load to Page Buffer (74H)
/ Page Buffer to Flash (0EH/D0H)
Single data load to the page buffer is performed by writing 74H
followed by a second write specifying the column address and
data. Distinct data up to 128word can be loaded to the page
buffer by this two-command sequence. On the other hand, all of
the loaded data to the page buffer is programed simultaneously
by writing Page Buffer to Flash command of 0EH followed by the
confirm command of D0H. After completion of programing the
data on the page buffer is cleared automatically.
This command is valid for only Bank(I) alike Word Program.
Clear Page Buffer Command (55H)
Loaded data to the page buffer is cleared by writing the Clear
Page Buffer command of 55H followed by the Confirm command
of D0H. This command is valid for clearing data loaded by Single
Data Load to Page Buffer command.
Suspend/Resume Command (B0H/D0H)
Writing the Suspend command of B0H during block erase
operation interrupts the block erase operation and allows read out
from another block of memory. Writing the Suspend command of
B0H during program operation interrupts the program operation
and allows read out from another block of memory. The Bank
address is required when writing the Suspend/Resume Command.
The device continues to output Status Register data when read,
after the Suspend command is written to it. Polling the WSM
Status and Suspend Status bits will determine when the erase
operation or program operation has been suspended. At this
point, writing of the Read Array command to the CUI enables
reading data from blocks other than that which is suspended.
When the Resume command of D0H is written to the CUI,
the WSM will continue with the erase or program processes.
Block Erase / Confirm Command (20H/D0H)
Automated block erase is initiated by writing the Block Erase
command of 20H followed by the Confirm command of D0H. An
address within the block to be erased is required. The WSM
executes iterative erase pulse application and erase verify
operation.
Program Commands
A)Word/Byte Program (40H)
Word program is executed by a two-command sequence. The
Word Program Setup command of 40H is written to the
Command Interface, followed by a second write specifying the
address and data to be written. The WSM controls the program
pulse application and verify operation. The Word Program
Command is Valid for only Bank(I).
B)Page Program for Data Blocks (41H)
Page Program for Bank(I) and Bank(II) allows fast programming of
128words/256bytes of data. Writing of 41H initiates the page
program operation for the Data area. From 2nd cycle to
129th cycle, write data must be serially inputted. Address A6-A0
have to be incremented from 00H to 7FH. After completion of data
loading, the WSM controls the program pulse application and verify
operation.
DATA PROTECTION
The Flash Memory of M6MGB/T162S4BVP provides selectable
block locking of memory blocks. Each block has an associated
nonvolatile lock-bit which determines the lock status of the block.
In addition, the Flash Memory has a master Write Protect pin
(F-WP#) which prevents any modifications to memory blocks
whose lock-bits are set to "0", when F-WP# is low. When F-WP#
is high, all blocks can be programmed or erased regardless of
the state of the lock-bits, and the lock-bits are cleared to "1" by
erase. See the BLOCK LOCKING table on P.9 for details.
Power Supply Voltage
When the power supply voltage (F-VCC) is less than V
V
CC Lock-Out voltage, the device is set to the Read-only mode.
Regarding DC electrical characteristics of V
A delay time of 2 us is required before any device operation is
initiated. The delay time is measured from the time F-Vcc reaches
F-Vccmin (2.7V).
During power up, F-RP#=GND is recommended. Falling in Busy
status is not recommended for possibility of damaging the device.
MEMORY ORGANIZATION
The Flash Memory of M6MGB/T162S4BVP has one 16Kword boot
block, seven 16Kword parameter blocks, for Bank(I) and
twenty-eight 32Kword main blocks for Bank(II). A block is erased
independently of other blocks in the array.
