As the Erasealgorithmflow chart shows,whenthe
data read during Erase Verify is not FFh, another
Erase operationis performedand verification con-
tinuesfromthe addressofthelastverifiedbyte.The
command is terminated by writing another valid
command to the command register (for example
Program or Reset).
Program and Program Verify Modes.
The Pro-
gramModeisset-upbywriting40htothecommand
register. This is followed by a second write cycle
which latches the address and data of the byte to
be programmed.The rising edge of W during this
secind cycle starts the programming operation.
ProgrammingisfollowedbyaProgramVerifyofthe
datawritten.
ProgramVerify Modeis set-up bywriting C0h tothe
command register. The rising edgeof W duringthe
set-up of the ProgramVerify Mode stops the Pro-
gramming operation. The following read cycle, of
the address already latched during programming,
is made with an internally generated margin volt-
ageapplied,readingvaliddataindicatesthatallbits
havebeen programmed.
ResetMode.
Thiscommandis usedto safelyabort
Erase or Program Modes. The Reset Mode is
set-up and performed by writing FFh two times to
the command register. The command should be
followed by writing a valid command to the the
command register (for exampleRead).
