... ERASURE: Before a byte/word can be reprogrammed, it must be erased. The erased state of memory bits is a logical “1”. The entire device can be erased by using the Chip Erase com- mand or individual sectors can be erased by using the Sector Erase command. ...

... TOGGLE BIT: In addition to Data Polling the AT49BV/LV32X(T) provides another method for determining the end of a program or erase cycle. During a program or erase operation, suc- cessive attempts to read data from the memory will result in I/O6 toggling between one and zero. Once the program cycle has completed, I/O6 will stop toggling and valid data will be read. Examining the toggle bit may begin at any time during a program cycle. Please see “ ...

... The device also supports an erase suspend during a complete chip erase. While the chip erase is suspended, the user can read from any sector within the memory that is pro- tected. The command sequence for a chip erase suspend and a sector erase suspend are the same ...
