Remark Internal verify 2 is used in the above program example. Use internal verify 1 to verify s whole block.
Examples of operation when the interrupt-disabled time should be minimized in self programming mode are
(1) Erasure to blank check
<1> Specification of block erase command (<1> to <5> in 14.8.6)
<2> Mode is shifted from normal mode to self programming mode (<1> to <7> in 14.8.4)
<3> Execution of block erase command
<4> Mode is shifted from self programming mode to normal mode (<1> to <6> in 14.8.5)
<5> Specification of block blank check command (<1> to <5> in 14.8.7)
<6> Mode is shifted from normal mode to self programming mode (<1> to <7> in 14.8.4)
<7> Execution of block blank check command
<8> Mode is shifted from self programming mode to normal mode (<1> to <6> in 14.8.5)
