Information
address/data write combinations abort the Write Buffer Programming operation. The device goes
“busy.” The Data Bar polling techniques should be used while monitoring the last address location
loaded into the write buffer. This eliminates the need to store an address in memory because the
system can load the last address location, issue the program confirm command at the last loaded
address location, and then data bar poll at that same address. DQ7, DQ6, DQ5, DQ2, and DQ1
should be monitored to determine the device status during Write Buffer Programming.
The write-buffer “embedded” programming operation can be suspended using the standard sus-
pend/resume commands. Upon successful completion of the Write Buffer Programming operation,
the device returns to READ mode.
The Write Buffer Programming Sequence is ABORTED under any of the following conditions:
Load a value that is greater than the page buffer size during the “Number of Locations to Pro-
gram” step.
Write to an address in a sector different than the one specified during the Write-Buffer-Load
command.
Write an Address/Data pair to a different write-buffer-page than the one selected by the
“Starting Address” during the “write buffer data loading” stage of the operation.
Write data other than the “Confirm Command” after the specified number of “data load” cy-
cles.
The ABORT condition is indicated by DQ1 = 1, DQ7 = DATA# (for the “last address location
loaded”), DQ6 = TOGGLE, DQ5 = 0. This indicates that the Write Buffer Programming Operation
was ABORTED. A “Write-to-Buffer-Abort reset” command sequence is required when using the
write buffer Programming features in Unlock Bypass mode. Note that the Secured Silicon sector,
autoselect, and CFI functions are unavailable when a program operation is in progress.
Write buffer programming is allowed in any sequence of memory (or address) locations. These
flash devices are capable of handling multiple write buffer programming operations on the same
write buffer address range without intervening erases.
Use of the write buffer is strongly recommended for programming when multiple words are to be
programmed. Write buffer programming is approximately eight times faster than programming
one word at a time.
