... Read The AT49BV322A(T) is accessed like an EPROM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins are asserted on the out- puts. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention. ...

... Byte/Word Programming Once a memory block is erased programmed (to a logical “0” byte-by-byte word-by-word basis. Programming is accomplished via the internal device command register and is a four-bus cycle operation. The device will automatically generate the required internal program pulses ...

... During a program or erase operation, successive 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 ...
