(3)  Flash Memory Access in Sector Access Mode 
Figures 25.13 and 25.14 show the timing of writing to and reading from the NAND-type flash 
memory in sector access mode. 
Figure 25.13 shows the timing of writing to the 1-Gbit large-block flash memory. During the 
execution of sequential sector access spanning multiple pages, data are written to the flash 
memory with the timing shown in the figure for every page (2048 + 64 bytes).
