3.9 Program Operation
See Timing Diagrams 6.11
The Program operation is used to program data from the on-chip BufferRAMs into the NAND FLASH memory array.
The device has two 2KB data buffers, 1 Page (4KB + 128B) in size. A page has 8 sectors of 512B each main area and 16B spare area. The
device can be programmed in units of 8 sectors at once.
Addressing for program operation
Within a block, the pages must be programmed consecutively from the LSB (least significant bit) page of the block to MSB (most significant
bit) pages of the block. Random page address programming is prohibited. Once users start to write data on a certain page, the page is a LSB
page, therefore LSB page does not have to always be a page 0.
