... Read When the AT49BV320C( the read mode, with CE and OE low and WE high, the data stored at the memory location determined by the address pins are asserted on the outputs. The outputs are put in the high impedance state whenever high. This dual-line control gives designers flexibility in preventing bus contention. ...

... RESET pin, the device returns to the read mode, depending upon the state of the control inputs. 4.4 Erasure Before a word can be reprogrammed, it must be erased. The erased state of memory bits is a logical “1”. The individual sectors can be erased by using the Sector Erase command. 4.4.1 Sector Erase The device is organized into 71 sectors (SA0 - SA70) that can be individually erased ...

... The status register indicates the status of device operations and the success/failure of that oper- ation. The Read Status Register command causes subsequent reads to output data from the status register until another command is issued. To return to reading from the memory, issue a Read command. The status register bits are output on I/O7 - I/O0. The upper byte, I/O15 - I/O8, outputs 00H when a Read Status Register command is issued ...
