18.8.10 Examples of operation when command execution time should be minimized in self programming
explained below.
310
Examples of operation when the command execution time should be minimized in self programming mode are
(1) Erasure to blank check
Note Perform processing to shift to normal mode in order to return to normal processing.
Remark
<1> Mode is shifted from normal mode to self programming mode (<1> to <7> in 18.8.4)
<2> Execution of block erase
<3> Execution of block blank check
<4> Mode is shifted from self programming mode to normal mode (<1> to <6> in 18.8.5)
