Notes: 1. Sampled only, not 100% tested.
2. G may be delayed by up to tELQV - tGLQV after the falling edge of E without increasing tELQV.
3. To be considered only if the Reset pulse is given while the memory is in Erase or Program mode.

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 0.1µs and 15µs 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
