after the sixth rising edge of W or E output the
status register status bits.
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 erase failure. In such a situation, the Toggle bit
DQ2 can be used to determine which block is not
correctly erased. In the case of erase failure, a
Read/Reset RD instruction is necessary in order to
reset the P/E.C.
Chip Erase (CE) Instruction.
This instruction uses
six write cycles. The Erase Set-up command 80h
is written to address 5555h on the third cycle after
the two Coded cycles. The Chip Erase Confirm
command 10h is similarly written on the sixth cycle
after another two Coded cycles. If the second
command given is not an erase confirm or if the
Coded cycles are wrong, the instruction aborts and
the device 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 after the sixth rising edge of W or E
output the Status Register bits. During the execu-
tion of the erase by the P/E.C., Data Polling bit DQ7
returns ’0’, then ’1’ on completion. The Toggle bits
DQ2 and DQ6 toggle during erase operation and
