COMPATIBLE BLOCK ERASE
This device can be applied to the compatible block erase
algorithm shown in the following flowchart. This algorithm
allows to obtain faster erase time by the block (refer to
COMPATIBLE BLOCK ERASE FLOWCHART
page2) without any voltage stress to the device nor
deterioration in reliability of data.
START
For selected block(s),
All bits PGM"0"
