16,777,216-BIT (1,048,576 -WORD BY 16-BIT ) CMOS 3.3V-ONLY FLASH MEMORY & 4,194,304-BIT (262,144-WORD BY 16-BIT) CMOS SRAM Stacked-CSP (Chip Scale Package)
FUNCTION
The Flash Memory of M6MGB/T166S4BWG 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/T166S4BWG 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 F-OE#, high level input to F-WE# and F-RP#, and address signals to the address inputs (F-A19-F-A17,A16-A0) output the data of the addressed location to the data input/output ( D15-D0). 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 F-WE# to low level, while F-CE# is at low level and F-OE# is at high level. Address and data are latched on the earlier rising edge of F-WE# and F-CE#. Standard micro-processor write timings are used. Alternating Background Operation (BGO) The Flash Memory of M6MGB/T166S4BWG 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 F-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.
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.

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.
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 00000H and 00001H, 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 F-OE# or F-CE#. So F-CE# or F-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.
DATA PROTECTION 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 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 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. The Flash Memory of M6MGB/T166S4BWG 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 VLKO, Low V CC Lock-Out voltage, the device is set to the Read-only mode. Regarding DC electrical characteristics of VLKO, see P.10. A delay time of 2µs 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/T166S4BWG 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.
