Auto Block Erase
The Auto Block Erase operation starts on the rising edge of
WE
after the Erase Start command “D0h” which
follows the Erase Setup command “60h”. This two-cycle process for Erase operations acts as an extra layer of
protection from accidental erasure of data due to external noise. The device automatically executes the Erase
and Verify operations.
Multi Block Erase
The Multi Block Erase operation starts by selecting two block addresses before D0h command as in below
diagram. The device automatically executes the Erase and Verify operations and the result can be monitored by
checking the status by 71h status read command. For details on 71h status read command, refer to section
“Multi Page Program with Data Cache”.
Internal addressing in relation with the Districts
To use Multi Block Erase operation, the internal addressing should be considered in relation with the District.
• The device consists from 2 Districts.
• Each District consists from 1024 erase blocks.
• The allocation rule is follows.
District 0: Block 0, Block 2, Block 4, Block 6,···, Block 2046
District 1: Block 1, Block 3, Block 5, Block 7,···, Block 2047
Address input restriction for the Multi Block Erase
There are following restrictions in using Multi Block Erase
(Restriction)
Maximum one block should be selected from each District.
For example;
(60) [District 0] (60) [District 1] (D0)
(Acceptance)
There is no order limitation of the District for the address input.
For example, following operation is accepted;
(60) [District 1] (60) [District 0] (D0)
It requires no mutual address relation between the selected blocks from each District.
Make sure to terminate the operation with D0h command. If the operation needs to be terminated before D0h
command input, input the FFh reset command to terminate the operation.
