... 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. ...

Any commands written to the chip during the embedded programming cycle will be ignored hardware reset happens during programming, the data at the location being programmed will be corrupted. Please note that a data “0” cannot be programmed ...

... TOGGLE BIT: In addition to Data Polling the AT49BV322A(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 ...

RDY/BUSY: An open-drain READY/BUSY output pin provides another method of detecting the end of a program or erase operation. RDY/BUSY is actively pulled low during the internal program and erase cycles and is released at the completion of the cycle. ...
