BLOCK DIAGRAM DESCRIPTION

TheblockdiagramonPage5illustratesasimpliedarchitectureofMX29GA256EC/F.Eachblockintheblock

diagramrepresentsoneormorecircuitmodulesintherealchipusedtoaccess,erase,program,andreadthe

memoryarray.

The"CONTROLINPUTLOGIC"blockreceivesinputpinsCE#,OE#,WE#,RESET#,andWP#/ACC.Itcreates

internaltimingcontrolsignalsaccordingtotheinputpinsandoutputstothe"ADDRESSLATCHANDBUFFER"

tolatchtheexternaladdresspinsA0-AM(A23).Theinternaladdressesareoutputfromthisblocktothemainar-

ray and decoders composed of "X-DECODER", "Y-DECODER", "Y-PASS GATE",AND "FLASHARRAY". The

X-DECODER decodes the word-lines of the flash array, while the Y-DECODER decodes the bit-lines of the

asharray.Thebitlinesareelectricallyconnectedtothe"SENSEAMPLIFIER"and"PGMDATAHV"selectively

throughtheY-PASSGATES.SENSEAMPLIFIERSareusedtoreadoutthecontentsoftheashmemory,while

the "PGM DATA HV" block is used to selectively deliver high power to bit-lines during programming. The "I/O

BUFFER"controlstheinputandoutputontheQ0-Q15pads.Duringreadoperation,theI/OBUFFERreceives

datafromSENSEAMPLIFIERSanddrivestheoutputpadsaccordingly.Inthelastcycleofprogramcommand,

the I/O BUFFER transmits the data on Q0-Q15 to "PROGRAM DATA LATCH", which controls the high power

driversin"PGMDATAHV"toselectivelyprogramthebitsinawordaccordingtotheuserinputpattern.

The"PROGRAM/ERASEHIGHVOLTAGE"blockcomprisesthecircuitstogenerateanddeliverthenecessary

highvoltagetotheX-DECODER,FLASHARRAY,and"PGMDATAHV"blocks.Thelogiccontrolmodulecom-

prises of the "WRITE STATE MACHINE, WSM", "STATE REGISTER", "COMMAND DATA DECODER", and

"COMMANDDATALATCH". When theuserissues a commandbytoggling WE#, thecommandonQ0-A15 is

latchedintheCOMMANDDATALATCHandisdecodedbytheCOMMANDDATADECODER.TheSTATEREG-

ISTER receives the command and records the current state of the device. The WSM implements the internal

algorithmsforprogramoreraseaccordingtothecurrentcommandstatebycontrollingeachblockintheblock

Toperformareadoperation,thesystemaddressesthedesiredmemoryarrayorstatusregisterlocationbypro-

vidingitsaddressontheaddresspins andsimultaneouslyenablingthechipbydrivingCE#&OE#LOW, and

WE#HIGH.AftertheTceandToetimingrequirementshavebeenmet,thesystemcanreadthecontentsofthe

addressedlocationbyreadingtheData(I/O)pins.IfeithertheCE#orOE#isheldHIGH,theoutputswillremain

tri-statedandnodatawillappearontheoutputpins.

PAGE READ

WRITE OPERATION

Toperformawriteoperation,thesystemprovidesthedesiredaddressontheaddresspins,enablesthechipby

assertingCE#LOW,anddisablestheData(I/O)pinsbyholdingOE#HIGH.Thesystemthenplacesdatatobe

writtenontheData(I/O)pinsandpulsesWE#LOW.Thedevicecapturestheaddressinformationonthefalling

edgeofWE#andthedataontherisingedgeofWE#.Toseeanexample,pleaserefertothetimingdiagram

inFigure1onPage53.Thesystemisnotallowedto writeinvalid commands(commandsnotdenedinthis

datasheet)tothedevice.Writinganinvalidcommandmayputthedeviceinanundenedstate.

DEVICE RESET

DrivingtheRESET#pinLOWforaperiodofTrpormorewillreturnthedevicetoReadmode.Ifthedeviceisin

themiddleofaprogramoreraseoperation,theresetoperationwilltakeatmostaperiodofTready1beforethe

devicereturnstoReadmode.UntilthedevicedoesreturnstoReadmode,theRY/BY#pinwillremainLow(Busy

Status).

WhentheRESET#pinisheldatGND±0.3V,thedeviceonlyconsumesstandby(Isbr)current.However,thede-

vicedrawslargercurrentiftheRESET#pinisheldatavoltagegreaterthanGND+0.3Vandlessthanorequalto

Vil.

ItisrecommendedtotiethesystemresetsignaltotheRESET#pinoftheashmemory.Thisallowsthedevice

tobe resetwiththe systemandputsit inastate where thesystemcan immediatelybeginreading boot code

fromit.

STANDBY MODE

ThedeviceentersStandbymodewhenevertheRESET#andCE#pinsarebothheldHighexceptintheembed-

dedmode.Whileinthismode,WE#andOE#willbeignored,allDataOutputpinswillbeinahighimpedance

COMMAND OPERATIONS

READING THE MEMORY ARRAY

Readmodeisthedefaultstateafterpoweruporafteraresetoperation.Toperformareadoperation,pleasere-

fertoREADOPERATIONintheBUSOPERATIONSsectionabove.

If the device receives an Erase Suspend command while in the Sector Erase state, the erase operation will

pause(afteratimedelaynotexceeding20us)andthedevicewillenterErase-SuspendedReadmode.Whilein

theErase-SuspendedReadmode,datacanbeprogrammedorreadfromanysectornotbeingerased.Reading

fromaddresseswithinsector(s)beingerasedwillonlyreturnthecontentsofthestatusregister,whichisinfact

howthecurrentstatusofthedevicecanbedetermined.

If a program command is issued to any inactive (not currently being erased) sector during Erase-Suspended

Readmode,thedevicewillperformtheprogramoperationandautomaticallyreturntoErase-SuspendedRead

modeaftertheprogramoperationcompletessuccessfully.

WhileinErase-SuspendedReadmode,anEraseResumecommandmustbeissuedbythesystemtoreactivate

the erase operation.  The erase operation will resume from where is was suspended and will continue until it

completessuccessfullyoranotherEraseSuspendcommandisreceived.

Afterthememorydevicecompletesanembeddedoperation(automaticChipErase,SectorErase,orProgram)

successfully,itwillautomaticallyreturntoReadmodeanddatacanbereadfromanyaddressinthearray.Ifthe

duringtheoperations,thesystemmustperformaresetoperationtoreturnthedevicetoReadmode.

ThereareseveralstatesthatrequirearesetoperationtoreturntoReadmode:

1.Aprogramorerasefailure--indicatedbystatusregisterbitQ5goingHIGHduringtheoperation.Failuresdur-

ingeitherofthesestateswillpreventthedevicefromautomaticallyreturningtoReadmode.

2.ThedeviceisinAutoSelectmodeorCFImode.Thesetwostatesremainactiveuntiltheyareterminatedbya

resetoperation.

Inthetwosituationsabove,ifaresetoperation(eitherhardwareresetorsoftwareresetcommand)isnotper-

formed,thedevicewillnotreturntoReadmodeandthesystemwillnotbeabletoreadarraydata.

AUTOMATIC PROGRAMMING OF THE MEMORY ARRAY

ThedeviceprovidestheusertheabilitytoprogramthememoryarrayinWordmode.Aslongastheusersenters

thecorrectcycledened intheTable 3(including 2unlockcycles andtheA0H programcommand),any word

dataprovidedonthedatalinesbythesystemwillautomaticallybeprogrammedintothearrayatthespecied

location.

Aftertheprogramcommandsequencehasbeenexecuted,theinternalwritestatemachine(WSM)automatically

executesthealgorithmsandtimingsnecessaryforprogrammingandverication,whichincludesgeneratingsuit-
