1. Write timing characteristics during erase suspend are the same as WRITE-only opera-
tions.
Notes:
2. A WRITE operation can be terminated with either CE# or WE#.
3. Sampled, not 100% tested.
4. Write pulse width LOW (tWLWH or tELEH) is defined from CE# or WE# LOW (whichever
occurs last) to CE# or WE# HIGH (whichever occurs first). Thus, tWLWH = tELEH = tWLEH
= tELWH.
5. Write pulse width HIGH tWHWL or tEHEL) is defined from CE# or WE# HIGH whichever
occurs first) to CE# or WE# LOW whichever occurs last). Thus, tWHWL = tEHEL = tWHEL
tEHWL).
=
6. tWHVH or tWHCH/L must be met when transitioning from a WRITE cycle to a synchro-
nous BURST read.
7. VPP and WP# should be at a valid level until erase or program success is determined.
8. This specification is only applicable when transitioning from a WRITE cycle to an asyn-
chronous read. See spec tWHCH/L and tWHVH for synchronous read.
