2. The programming and erase count determine the number of times the erase operation
For example, if 1-word programming is done 2,048 times, each at a different address in
can be performed in each block.
a 4-Kbyte block and then the block is erased, this is counted as one erase count. If the
allowed programming and erase count are 100 times, each block can be erased 100
times.
