Erase Suspend (ES) Instruction. The Block
Erase operation may be suspended by this instruc-
tion which consists of writing the command B0h
without any specific address. No Coded cycles are
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
togglingwhen the P/E.C. is suspended.The Toggle
bits will stop toggling between 0.1 s and 15 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 toggling and DQ6 at ’1’. A Read from
