Command Definitions
Device operations selected writing specific address data sequences into command register. Writing incorrect address data values writing them improper sequence will reset device read mode. Table defines valid register command sequences. Note that Erase Suspend (B0H) Erase Resume (30H) commands valid only while Sector Erase operation progress. Moreover, both Read/ Reset Commands functionally equivalent, resetting device read mode.
MBM29F040C-55/-70/-90
Read/Reset Command
read reset operation initiated writing Read/Reset command sequence into command register. Microprocessor read cycles retrieve array data from memory. device remains enabled reads until command register contents altered. device will automatically power-up read/reset state. this case, command sequence required read data. Standard microprocessor read cycles will retrieve array data. This default value ensures that spurious alteration memory content occurs during power transition. Refer Read Characteristics Waveforms specific timing parameters.
Autoselect Command
Flash memories intended applications where local alters memory contents. such, manufacture device codes must accessible while device resides target system. PROM programmers typically access signature codes raising high voltage (VID 11.5 12.5). However, multiplexing high voltage onto address lines generally desired system design practice. device contains Autoselect command operation supplement traditional PROM programming methodology. operation initiated writing Autoselect command sequence into command register. Following command write, read cycle from address XX00H retrieves manufacture code 04H. read cycle from address XX01H returns device code A4H. (see Table manufacturer device codes will exhibit parity with (DQ7) defined parity bit. Sector state (protection unprotection) will informed address XX02H. Scanning sector addresses (A16, A17, A18) while (A6, will produce logical device output protected sector. programming verification should perform margin mode protected sector. (See Table terminate operation, necessary write Read/Reset command sequence into register, also write Autoselect command during operation, execute after writing Read/Reset command sequence.
Byte Programming
device programmed byte-by-byte basis. Programming four cycle operation. There "unlock" write cycles. These followed program setup command data write cycles. Addresses latched falling edge whichever happens later data latched rising edge whichever happens first. rising edge (whichever happens first) begins programming. Upon executing Embedded Program Algorithm command sequence, system required provide further controls timings. device will automatically provide adequate internally generated program pulses verify programmed cell margin. automatic programming operation completed when data equivalent data written this (See Write Operation Status section.) which time device returns read mode addresses longer latched. (See Table Hardware Sequence Flags.) Therefore, device requires that valid address device supplied system this particular instance time. Hence, Data Polling must performed memory location which being programmed. commands written chip during this period will ignored. Programming allowed sequence across sector boundaries. Beware that data cannot programmed back "1". Attempting either hang device (Exceed timing limits.), result apparent success according data polling algorithm read from reset/read mode will show that data still "0". Only erase operations convert "0"s "1"s. Figure illustrates Embedded ProgramAlgorithm using typical command strings operations.
MBM29F040C-55/-70/-90
Chip Erase
Chip erase cycle operation. There "unlock" write cycles. These followed writing "set-up" command. more "unlock" write cycles then followed chip erase command. Chip erase does require user program device prior erase. Upon executing Embedded Erase Algorithm command sequence device will automatically program verify entire memory zero data pattern prior electrical erase. system required provide controls timings during these operations. automatic erase begins rising edge last pulse command sequence terminates when data (see Write Operation Status section.) which time device returns read mode. Figure illustrates Embedded Erase Algorithm using typical command strings operations.
Sector Erase
Sector erase cycle operation. There "unlock" write cycles. These followed writing "set-up" command. more "unlock" write cycles then followed Sector Erase command. sector address (Any address location within desired sector.) latched falling edge while command (Data 30H) latched rising edge time-out from rising edge last sector erase command will initiate sector erase command(s). Multiple sectors erased concurrently writing cycle operations described above. This sequence followed with writes Sector Erase command addresses other sectors desired concurrently erased. time between writes must less than otherwise that command will accepted. recommended that processor interrupts disabled during this time guarantee this condition. interrupts re-enabled after last Sector Erase command written. time-out from rising edge last will initiate execution Sector Erase command(s). another falling edge occurs within time-out window timer reset. (Monitor determine sector erase timer window still open, section DQ3, Sector Erase Timer.) command other than Sector Erase Erase Suspend during this time-out period will reset device read mode, ignoring previous command string. Resetting device once execution begun will corrupt data sector. that case, restart erase those sectors allow them complete. (Refer Write Operation Status section Sector Erase Timer operation.) Loading sector erase buffer done sequence with number sectors Sector erase does require user program device prior erase. device automatically programs memory locations sector(s) erased prior electrical erase. When erasing sector sectors remaining unselected sectors affected. system required provide controls timings during these operations. automatic sector erase begins after time from rising edge pulse last sector erase command pulse terminates when data (See Write Operation Status section.) which time device returns read mode. During execution Sector Erase command, only Erase Suspend Erase Resume commands allowed. other commands will reset device read mode. Data polling must performed address within sectors being erased. Figure illustrates Embedded EraseAlgorithm using typical command strings operations.

Erase Suspend
Erase Suspend command allows user interrupt Sector Erase operation then perform data reads from programs sector being erased. This command applicable ONLY during Sector Erase operation which include time-out period sector erase. Erase Suspend command will ignored written during Chip Erase operation Embedded Program Algorithm. Writting Erase Suspend command during Sector Erase time-out results immediate termination time-out period suspension erase operation. other command written during Erase Suspend mode will ignored except Erase Resume command. Writing Erase Resume command resumes erase operation. addresses "DON'T CARES" when writing Erase Suspend Erase Resume command. When Erase Suspend command written during Sector Erase operation, device will take maximum suspend erase operation. When devices have entered erase-suspended mode, will logic "1", will stop toggling. user must address erasing sector reading determine erase operation been suspended. Further writes Erase Suspend command ignored. When erase operation been suspended, devices default erase-suspend-read mode. Reading data this mode same reading from standard read mode except that data must read from sectors that have been erase-suspended. Successively reading from erase-suspended sector while device erase-suspend-read mode will cause toggle. (See section DQ2.) After entering erase-suspend-read mode, user program device writing appropriate command sequence Program. This Program mode known erase-suspend-program mode. Again, programming this mode same programming regular Program mode except that data must programmed sectors that erase-suspended. Successively reading from erase-suspended sector while devices erase-suspend-program mode will cause toggle. erasesuspended Program operation detected Data polling DQ7, Toggle (DQ6) which same regular Program operation. Note that must read from Program address while read from address. resume operation Sector Erase, Resume command (30H) should written. further writes Resume command this point will ignored.
