Internal addressing in relation with the Districts
To use Multi Page Program operation, the internal addressing should be considered in relation with the
District.
• The device contains four chips of NAND EEPROM.
• Each internal chip consists from 2 Districts.
• Each District consists from 2048 erase blocks.
• The allocation rule is follows.
(a) District 0: Block 0, Block 2, Block 4, Block 6,···, Block 4094
(b) District 1: Block 1, Block 3, Block 5, Block 7,···, Block 4095
(c) District 0: Block 4096, Block 4098, Block 4100, Block 4102,···, Block 8190
(d) District 1: Block 4097, Block 4099, Block 4101, Block 4103,···, Block 8191
Combination of (a) and (b) or (c) and (d) can only be selected.
Address input restriction for the Multi Page Program with Data Cache operation
There are following restrictions in using Multi Page Program with Data Cache;
(Restriction)
District0 and District1 should be selected within the same chip.
Maximum one block should be selected from each District.
Same page address (PA0 to PA5) within two districts has to be selected.
For example;
(80) [District 0, Page Address 0x00000] (11) (81) [District 1, Page Address 0x00040] (15 or 10)
(80) [District 0, Page Address 0x00001] (11) (81) [District 1, Page Address 0x00041] (15 or 10)
(Acceptance)
There is no order limitation of the District for the address input.
For example, following operation is accepted;
(80) [District 0] (11) (81) [District 1] (15 or 10)
(80) [District 1] (11) (81) [District 0] (15 or 10)
It requires no mutual address relation between the selected blocks from each District.
Operating restriction during the Multi Page Program with Data Cache operation
(Restriction)
The operation has to be terminated with “10h” command.
Once the operation is started, no commands other than the commands shown in the timing diagram is allowed
to be input except for Status Read command and reset command.
