development; mass production scheduled to start in the 3rd quarter of 2003.)
The E/W times are defined to be per-block erasure times. For example, assume a case whereby a
4-Kbyte Block A is programmed one word at a time and erased once all 2048 write operations
have completed. In this case, the block is considered to have been written and erased once.
If a product is 100 times E/W, each block in it can be erased up to 100 times. When 10,000 times
E/W, Block A and Block B can each be erased up to 10,000 times. All other blocks can each be
erased up to 1000 times.
