Internal addressing in relation with the Districts
To use Multi Block Program operation, the internal addressing should be conscious in relation with the
District.
· The device consists of 2-chips, each of which have 4 Districts.
· Each District consists from 1024 erase blocks.
· The allocation rule is follows.
Chip 0, District 0: Block 0, Block 4, Block 8, Block 12, ···.., Block 4092
Chip 0, District 1: Block 1, Block 5, Block 9, Block 13, ···.., Block 4093
Chip 0, District 2: Block 2, Block 6, Block 10, Block 14, ···.., Block 4094
Chip 0, District 3: Block 3, Block 7, Block 11, Block 15, ···.., Block 4095
Chip 1, District 0: Block 4096, Block 4100, Block 4104, Block 4108, ···.., Block 8188
Chip 1, District 1: Block 4097, Block 4101, Block 4105, Block 4109, ···.., Block 8189
Chip 1, District 2: Block 4098, Block 4102, Block 4106, Block 4110, ···.., Block 8190
Chip 1, District 3: Block 4099, Block 4103, Block 4107, Block 4111, ···.., Block 8191
Address input restriction for the Multi Block Program operation
In selecting the blocks for the Multi Block Program operation, following is the restriction and acceptance.
(Restriction)
It is prohibited to select blocks across 2-chips.
Maximum one block should be selected from each District.
The data input operation should be started from the same number page of the each selected block and then, the
page number in the blocks should be same number at the same time programming.
(Acceptance)
There is no order limitation of the District for the address input.
Any number of the District can be select for the programming.
So, for example, following operation is in acceptance.
(80) [District 2] (11) (80) [District 0] (11) (80) [District 1] (15)
It requires no mutual address relation between the selected blocks from each District.
Operating restriction during the Multi Block Program operation
(Restriction)
Starting from 1st page data input, until issuing “10H” command, any other command out of defined sequence
can not be issued except Status Read command and Reset command.
(Acceptance)
The data input operation can be terminated with “10H” command instead of “15H” command in the middle of
the page number in the block.
In this case the Status represents the reflected value accumulated from 1st page programming of this sequence
and up to the last page programming terminated by “10H” command.
Status Read operation
Untill the Ready condition after the programming terminated by “10H” command, effective bit in the Status
data is limited on Ready/Busy bit.
In other words, Pass/Fail condition can be checked only in the Ready condition after “10H” command.
