During the execution of the erase by the P/E.C.,
the memory accepts only the Erase Suspend ES
and Read/Reset RD instructions. Data Polling bit
DQ7 returns ’0’ while the erasure is in progress
and ’1’ when it has completed. The Toggle bit DQ2
and DQ6 toggle during the erase operation. They
stop when erase is completed. After completion
the Status Register bit DQ5 returns ’1’if there has
been an erasefailure. In such a situation, theTog-
gle bit DQ2 can be used to determine which block
is notcorrectly erased. In the caseof erase failure,
a Read/ResetRD instruction is necessary inorder
to reset the P/E.C.
Chip Erase (CE) Instruction.
This
uses six write cycles. The Erase Set-up command
80h is written to address AAAh in the Byte-wide
configuration or the address 555h in the Word-
instruction
wide configuration on the third cycle after the two
Coded cycles. The Chip Erase Confirm command
10h is similarly written on the sixth cycle after an-
other two Coded cycles. If the second command
given is not an erase confirm or if the Coded cy-
cles are wrong, the instruction aborts and the de-
vice is reset to Read Array. It is not necessary to
program the array with 00h first as the P/E.C. will
automatically do this before erasing it to FFh.
Read operations afterthe sixth rising edge of W or
E output the Status Register bits. During the exe-
cution of the erase by the P/E.C., Data Polling bit
DQ7 returns ’0’,then ’1’oncompletion. TheToggle
bits DQ2 and DQ6 toggle during erase operation
and stop when erase is completed. After comple-
tion the Status Register bit DQ5 returns ’1’if there
has been an Erase Failure.
