Translation - Japanese: ブロック消去について - KBA215751 - Community Translated (JA)
What would happen if a block erase was issued to address 0000 1000 or some other address on a 4K but not 64K boundary?
If the address belongs to a particular block, the entire block will get erased. It need not necessarily be at the boundary. The Block Erase will execute as long as Block addresses are latched.
