Block Erase (BE) Instruction. This
instruction
uses a minimum of six write cycles. The Erase
Set-up command 80h is written to address AAAh
in the Byte-wide configuration or address 555h in
the Word-wide configuration on third cycle after
the two Coded cycles. The Block Erase Confirm
command 30h is similarly written on the sixth cycle
after another two Coded cycles. During the input of
the second command an address within the block
to be erased is given and latched into the memory.
Additional block Erase Confirm commands and
block addresses can be written subsequently to
erase other blocks in parallel, without further Cod-
ed cycles. The erase will start after the erase tim-
eout period (see Erase Timer Bit DQ3 description).
Thus, additional Erase Confirm commands for oth-
er blocks must be given within this delay. The input
of a new Erase Confirm command will restart the
timeout period. The status of the internal timer can
be monitored through the level of DQ3, if DQ3 is ’0’
the Block Erase Command has been given and
the timeout is running, if DQ3 is ’1’, the timeout has
expired and the P/E.C. is erasing the Block(s). If
the second command given is not an erase con-
firm or if the Coded cycles are wrong, the instruc-
tion aborts, and the device is reset to Read Array.
It is not necessary to program the block with 00h
as the P/E.C. will do this automatically before to
erasing to FFh. Read operations after the sixth ris-
ing edge of W or E output the status register status
bits.
