The 4GB memory module includes 4,096 blocks, each block contains 128 pages and each page includes 8640 bytes(data section of 8192+stanby section of 448). The programming and reading operation all base on page as units and erase operation bases on block as unit.

At most five cycles are needed for addressing : two for column address to address specific of each ;3 cycles are used for row address to address the specific page of block. Due to different units, writing operation uses five address cycles and programming operation uses five address cycles, in which the byte address is 0, erase operation uses three address cycles, in which the page address is 0.
