Erase Suspend (ES) Instruction.
The Block
Eraseoperationmay besuspendedbythisinstruc-
tion which consists of writing the command B0h
without anyspecificaddress.No Codedcyclesare
required. It permits reading of data from another
block and programming in another block while an
erase operation is in progress. Erase suspend is
accepted only during the Block Erase instruction
execution. Writing this command during Erase
timeout will, in addition to suspending the erase,
terminate the timeout. The Toggle bit DQ6 stops
togglingwhentheP/E.C.is suspended.The Toggle
bitswill stoptogglingbetween0.1

s after
the Erase Suspend (ES) command has been writ-
ten. The device will then automatically be set to
Read Memory Array mode. When erase is sus-
pended, a Read from blocks being erased will
output DQ2 togglingand DQ6 at ’1’. A Read from
a blocknot beingerasedreturnsvalid data.During
suspension the memory will respond only to the
Erase Resume ER and the Program PG instruc-
tions. AProgram operation can be initiatedduring
erase suspend in one of the blocks not being
erased. Itwillresultin bothDQ2andDQ6toggling
whenthedatais beingprogrammed.ARead/Reset
command will definitively abort erasure and result
in invalid data in the blocksbeing erased.
EraseResume(ER)Instruction.
Ifan EraseSus-
pend instruction was previously executed, the
erase operation may be resumed by giving the
command 30h, at any address, and without any
Coded cycles.
